To understand the complexity of the copper atom, there must first be an understanding of the basic structure of a general atom. Atoms are considered to be the simplest of matter; impossible to dice into smaller pieces. There are, however, subatomic particles that are the building blocks of the uncountable atoms that make up the earth: protons, neutrons, and electrons. The positively charge particles (protons) and neutrally charged particles (neutrons) make up the nucleus, the electrons surround the nucleus in a cloud. The configuration and number of electrons are crucial in making up and distinguishing elements. This leads us to the analysis of the element copper.
There are different ways in which the electrons are situated around a copper atom, and all atoms, for that matter. The first aspect of an electron configuration is the energy level (n number, or principle quantum number) the electrons reach. Each period of the period table represents an energy level. The number of electrons (equal to the number of protons) an element possesses, for the most part, dictates the highest energy level of an atom. Copper has an atomic number of 29 and is in the fourth period, thus its electrons reach the fourth energy level. The energy level determines the size of the orbital. Within each energy level, there is a sublevel that represents the shape of the path the electron takes. The number of possible shapes within an energy level is equal to the energy level number. In the copper atom, the electrons reach the fourth energy level, therefore there are four “l” values: l=0(s orbital), l=1(p orbital), l=2(d orbital), l=3(f orbital). There is then another sublevel called the magnetic quantum number. This value dictates the orientation of the orbi...

...diamagnetic species is slightly repelled by an external field. How the copper atom fills its orbitals is only one contributor to the distinctness of its character; isotopes are another.
There is even more uniqueness and variety to an atom of an element due to isotopes. An isotope is a derivation of an element: it maintains the same amount of protons (and thus, electrons) but has a different number of neutrons. Isotopes occur in different abundances. For the element of copper, there are 29 isotopes, only two of which are stable and not radioactive: 63Cu and 65Cu with abundances 69.15% and 30.85%, respectively.
Every element has a distinct make up due to the electron configuration, the number of protons (and thus electrons), the isotopes existing in nature, and many more factors. It is this innate uniqueness of elements that makes up almost every corner of the earth.
In "Energy Story" uses an explanation of atoms and tells us the parts of an atom and its structure. In the text it
Just as the title of the chapter suggests, the main focus of Chapter 11 is how elements found on the Periodic Table are not always what they appear. Kean begins this chapter with describing how elements can be unpredictable in some conditions, and uses example from the past to...
Nowadays this element more active or used for infrastructures, electronics goods, and other services, this element also we call it a Dr. Copper element because of high levels of sense of Ph.D. economic benefits. Copper has 20 protons and electrons with the symbol of Cu. In 21 century the market of this element goes up to 20 million tons a year buy and sell in the world trades scale in three big cities in the world such as New York, London, and Shanghai. Cu more necessary for wire, electronics, and computer chips; Copper also helps us to away bacteria

The interior structure of Earth is chemically divided into an outer solid crust, the mantle, a liquid outer core, and a solid inner core. The core is largely composed of iron, along with nickel and silicon. Other lighter elements are usually in the crust.
The Pauli exclusion principle is defined by Dr. Steven S. Zumdahl, "In a given atom no two electrons can have the same set of four quantum numbers." Due to this principle, only two electrons can inhabit a single energy level. The electrons that share the same energy level have opposite intrinsic angular momentums which is more commonly known as "spin". To determine the direction of the spin the angular momentum vector is analyzed.
Isotopes refer to 1 of 2 or more atoms with the same atomic number but different numbers of neutrons. The atom copper has two stable isotopes. They are 63Cu and 65Cu. 63Cu has an isotope atomic mass (in atom) of 62.9295989 and a natural abundance (in atom %) of 69.17. 65Cu has an isotope atomic mass (in atom) of 64.9277929 and a natural abundance (in atom %) of 30.83.
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...
Isotopes: Atoms of the same element (same atomic number) but with differing numbers of neutrons, different mass numbers.
The most unique characteristic of the Earth would be that it contains life on every part of the planet. A long time ago though there was no life on Earth, approximately 4.6 billion years ago. Emmanuel Kant was the philosopher that created the most widely held theory of the origin of the Earth, and the Solar System. The same theory was later advanced by the French Mathematician Pierre-Simon Laplace. Both of them had come up with the theory that the Sun and planets were condensed from a Nebula, which since then has been supported from data that more powerful spectrometers and telescopes have collected.
The Periodic Table is based around the Atomic Theory. Firstly people believed that everything was made up the four elements Earth, Fire, Wind, and Water. This theory evolved into everything being made up of atoms. Breakthroughs throughout history such as the discoveries of the nucleus, protons, neutrons and electrons have pushed this theory forward to where it is today.
To start off, learning the Bohr-Rutherford diagrams in grade nine was a very big confusion for me. I had never fully understood how many shells should go around the nucleus nor did I know how to do the many calculations. As I progressed into grade ten, the teachings became easier. The review shows an example such as in the the bohr diagram, a nucleus is in the center, which is a little circle, and following that there are shells surrounding it containing electrons. Each ring can only hold a certain amount of electrons, and so the first shell around the nucleus can hold a maximum of 2 electrons, the next shell is able to hold a maximum of 8 electro...
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.
This law states that, “when elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties” (textbook). From that, the modern periodic table was born; “each new horizontal row of the table corresponds to the beginning of a new period because a new principal energy level is being filled with electrons” (textbook).
In chemistry, metals compose a great number of the periodic table elements. Each metal has its own characteristic mass,
