The main components that form the atom are protons, neutrons and electrons. They are arranged in a specific way. Protons and neutrons are in the nucleus and the electrons follow an orbit surrounding it. There are about two stable copper isotopes. One has a mass of about 63 with a natural abundance of about 70%. The other has a mass of about 65 with an about 31 of natural abundance. In the copper atom there are about 29 electrons. Why exactly 29? Well the atomic number of an element is the amount of protons and electrons. So to find the amount of electrons, you look at the atomic number. In this case, the atomic number for copper is 29, which tells us there are 29 electrons. Electrons are distributed into shells, subshells, and orbitals of copper.

    Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.

  • Hydrogen: A Utile Element

    634 Words  | 2 Pages

    Elements are the basic building blocks of matter due to the fact that they are chemically the simplest substances. Whether we can find them in the air or in our gold/silver necklaces, elements are everywhere! One essential element is hydrogen, the first element on the period table (located under Group 1 as an alkaline metal) is composed of a single proton and electron; therefore having an atomic number and atomic mass of 1 and electron configuration of 1s1. In fact, hydrogen is the lightest, simplest and most commonly found chemical element in the universe (it makes up about 90% of the universe by weight). Interestingly enough, the heavier elements on the periodic table were either made from hydrogen or other elements that were made from hydrogen. The most common isotope formed of hydrogen is protium, with 1 proton and no neutrons. Hydrogen can also exist as both positively or negatively charged. The physical form of hydrogen at room temperature is a colorless and odorless gas. Hydrogen gas is extremely flammable and because of this chemical property, it is used as fuel for the main engine of space shuttles. Hydrogen is an important element and has received a lot of recognition throughout history for its usefulness.

  • Lead: The Most Important To The Structure And Chemical Properties Of Lead

    723 Words  | 2 Pages

    Lead is commonly referred to as Pb due to its chemical symbol on the periodic table (7). The Element as has an atomic number of 82 (7). From its atomic number, scientists can conclude that a natural element of lead contains a total of 82 protons, and 82 electrons (8). Lead also has an atomic mass of 207.2 (7). Being that the atomic mass is the number of protons plus the number of neutrons, scientists concludes that an atom of lead contains 125 neutrons along with the 82 protons (8). Lead is considered a poor metal on the periodic table. Lead is also in the p block of elements which means that its valence electrons will be in a p shell (8). Overall, the periodic table is a prime way to learn about the basics of

    While all atoms of the same element have the same number of protons, it is possible for atoms of one element to have different numbers of neutrons. Atoms of the same element with different numbers of neutrons are called isotopes . For example, all atoms of the element carbon have 6 protons, but while most carbon atoms have 6 neutrons, some have 7 or 8. Isotopes are named by giving the name of the element followed by the sum of the neutrons and protons in the isotope's nucl...

  • Dimitri Mendeleev: The Periodic Table Of Elements In Chemistry

    985 Words  | 2 Pages

    The first theory to do with the atom was by Democritus and Leucippus who first proposed the idea of the atom as an invisible particle that all matter is made of. However, the first real discovery of an element, besides those like Gold and Silver etc. (which people had been aware of before written history) was phosphorus, which was discovered by Henning Brand in 1649. In 1787, a French chemist called Antoine Lavoisier, made a list of all 33 known elements of the time. Between 1649 and 1869, the Periodic table was added to and in 1869 a total of 63 elements had been discovered. In 1864, John Newlands made a huge advancement in the arranging of these elements, as he was able to sort them in order of atomic weights and was also able to observe similar properties between elements. The creation of the Periodic table, however is considered to be done by Russian scientist Dimitri Mendeleev who proposed a table as a classification system for all of the elements that had been discovered and he even left spaces for elements that had not yet been discovered, but he predicted they would. The Periodic table contin...

    Dalton’s atomic theory says that each element contained its own number of atoms. Each element had its own size and weight. Dalton’s idea said that all things are made of small bits of matter this bits of matter where too small to be seen even with a microscope. Scientist began to think these small bits of matter where responsible for chemical changes. They thought that when these bits of matter combined a chemical change took place. Dalton assumed that there was a special pattern in the elements and was partly responsible for the periodic table.

    The next big step in the discovery of the atom was the scientific test that proved the existence of the atom. After the discovery of the atom we had the discovery of subatomic particles. With the discovery of the subatomic particles came the research, which came from experiments that were made to find out more about the subatomic particles. This research is how we uncovered that most of the weight of an atom is from its nucleus. With the gold foil experiment, tested by Ernest Rutherford, he discovered the existence of the positively charged nucleus. He proved this when the experiment was happening, a small fraction of the photons th...

  • History of the Periodic Table

    672 Words  | 2 Pages

    Things are very different from each other, and can be broken down into small groups inside itself, which was then noticed early by people, and Greek thinkers, about 400BC. Which just happened to use words like "element', and `atom' to describe the many different parts and even the smallest parts of matter. These ideas were around for over 2000 years while ideas such as `Elements' of Earth, Fire, Air, and Water to explain `world stuff' came and went. Much later, Boyle, an experimenter like Galileo and Bacon, was influenced much by Democritus, Gassendi, and Descartes, which lent much important weight to the atomic theory of matter in the 1600s. Although it was Lavoisier who had divided the very few elements known in the 1700's into four different classes, and then John Dalton made atoms even more believable, telling everyone that the mass of an atom was it's most important property. Then in the early 1800's Dobereiner noted that the similar elements often had relative atomic masses, and DeChancourtois made a cylindrical table of elements to display the periodic reoccurrence of properties. Cannizaro then determined atomic weights for the 60 or so elements known in the 1860s, and then a table was arranged by Newlands, with the many elements given a serial number in order of their atomic weights, of course beginning with Hydrogen. That made it clear that "the eighth element, starting from a given one, is a kind of a repeat of the first", which Newlands called the Law of Octaves.

  • Essay On The Periodic Table

    1598 Words  | 4 Pages

    The periodic table, used worldwide by scientists, teachers and students, for quick location of information about elements. The periodic table did not come by overnight though, the periodic table is a table formed from years of work, on the atomic structure. It all started years back with Democritus and his discovery of the atom. This was followed up by John Dalton many years down the track, after elements had been discovered Dalton attempted to create a way to make the elements easier to remember. 84 years later, JJ Thomson discovered electrons, which were key to the periodic table, and in 1889, Dmitri Mendeleev invented the periodic table. Years later Henry Moseley worked out how to measure atomic numbers of elements, and just 9 years after Neil Bohr explained the structure of the atom which further explained why Mendeleev had placed each element in a specific row or column. Finally James Chadwick discovered the neutron in 1922.

  • Importance Of Octet Rule

    Atom is referred to as the smallest and unnoticeable unit of matter. However, ions are atoms in which the number of protons and electrons are not the same. Therefore, ions can either be negatively and positively charged. Atom is made up of neutrons, protons, and electrons. The neutrons and protons make the nucleus of an atom while the electrons surround atom’s nucleus. Atom is electrically neutral because the number of electrons and protons are the same. Neutral Magnesium (Mg) is an atom, and it has 12 electrons and 12 electrons giving it a mass number of 24g/mole. Magnesium easily loses two electrons in its valence shell to be positively charged (cation), the number of protons are greater than the number of electrons in this case. Neutral oxygen (O) with eight electrons and eight protons is an atom. Oxygen atom easily acquire two extra electrons to make it valance shell complete and to become negatively charged; in this case, the number of electrons is more than the number of protons hence it is known anion (Smirnov, 2003). When an atom loses the electrons in their valence shell to become a cation, its atomic radius is always larger than it ionic radius. When an atom attracts electrons to its valence shell to become anion its atomic radius and ionic radius are the same (Housecroft, and Sharpe
