Rounding up, this means that the number of neutrons copper has is 64 (mass number) minus 29 (protons), so it has 35 neutrons. However, the mass number has a decimal place. This is due to the fact that the mass number is an average of all of the masses of the isotopes of an element, taking into account the abundances of each kind of isotope. Isotopes are atoms that have fewer or more neutrons than typical for that atom.

Protons always have negative charges. Then finally the neutron is a neutral charge or a charge of zero. If the charge of the whole atom it zero that means there are an equal number of positive and negative pieces. An electron can be found anywhere around the nucleus, and the protons and neutrons are in the nucleus. You can not pin point were the electrons are but the area that it can be in is called a shell.
Protons have a relative charge of +1, while neutrons have a relative charge of 0. Electrons then surround the nucleus at different energy levels. Electrons have a relative charge of -1, but their relative mass is much smaller than that of protons or neutrons. They have a relative mass of approximately 1/1836 atomic mass units. The number of protons in an atom defines its element; only atoms with 29 protons are copper atoms, and all atoms with 29 protons are copper atoms.
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.
An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels.
And quarks also comprise mesons. Among those different kinds of quarks, up quarks and down quarks are the most common ones. Most importantly, none of those quarks can exist as a single particle, because their masses are very small. This phenomenon is called “quantum confinement” and states that quarks cannot be observed independently, only confined in hadrons. Quark have small electric charge values, usually -1/3 or +2/3 times the elementary charge.
Uuq-292 lost 3 neutrons, and afterwards the resulting isotope decayed further by alpha emission. 24494Pu + 4820Ca 292114Uuq 289114Uuq + 3(10n), this claims that superheavy elements can be made in the laboratory.

Electrons : Electrons are negatively charged particles with a mass of 1/1846th of an atomic mass unit. They are arranged in shells around the central nucleus. Useful definitions for atomic structure : Atomic number (Z) : The number of protons in the nucleus of an atom but is also equal to the number of electrons in the same atom (because atoms don't carry an overall charge - the positives balance the negatives!). Mass Number, (A) (or atomic mass) : The number of neutrons and protons in the nucleus of one atom of the element The atomic number and mass number of a particular element can be found from the periodic table. The atomic number is always displayed to the bottom left of the symbol for the element.
Orbits describe the chemical properties of dissimilar atoms (Encyclopedia Britannica. 2011). All electron orbits have a quantum number n and orbits with the same value of n make up a shell (Encyclopedia Britannica. 2011). Hydrogen, lithium, and sodium have like properties with one electron in the outermost shell (Encyclopedia Britannica.
This are arranged in layers, called energy levels, and have no mass. Only a certain number of electrons fit on each energy level, and it is this which affects the reactivity of certain materials and is also the way that the periodic table is arranged. The number of electrons in the outer energy level is the group in which the element is placed. The first level (nearest the nucleus) will only hold 2 electrons, the second holds 8, and the third also seems to be full when it has 8 electrons. If all of the energy levels in the atom are full populated with electrons, it is said to be stable, and in most cases, is therefore unreactive.
