The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10 -19 coulombs. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.

The sodium atom donates its valence electron to the chlorine atom and the chlorine atom receives that electron.Sodium is a chemical element with atomic number 11 which means there are 11 protons in its nucleus. The electron configuration of chlorine shows that the valence electrons of chlorine are seven. This valence electron participates in the formation of bonds with atoms of other elements. We know that the valence electron in sodium is one. Sodium participates in the formation of bonds through its valence electron. Since the last shell of a sodium-ion has eight electrons, the valence electrons of sodium ion(Na +) are eight. That is, in this case, the valency of the sodium ion is +1. The electron configuration shows that the sodium atom has acquired the electron configuration of neon. The electron configuration shows that sodium ion(Na +) have only two shells and the last shell has eight electrons. The electron configuration of sodium ion(Na +) is 1s 2 2s 2 2p 6. Sodium donates the electron of the last shell to form bonds and turns into a sodium ion(Na +). The elements that form bonds by donating electrons are called cations. The elements that have 1, 2, or 3 electrons in the last shell donate the electrons in the last shell during bond formation. How many valence electrons does sodium ion(Na +) have?

The electron configuration of sodium shows that there is an unpaired electron in the last orbit of sodium. The valence electrons determine the properties of the element and participate in the formation of bonds. The total number of electrons in the last shell after the electron configuration of sodium is called the valence electrons of sodium. The valence electron is the total number of electrons in the last orbit(shell). What are the valence electrons of sodium? Therefore, the number of neutrons in sodium is 12. We know that the atomic number of sodium is 11 and the atomic mass number is about 23(22.989769). That is, neutron number (n) = atomic mass number (A) – atomic number (Z) The number of neutrons in an element is obtained from the difference between the number of atomic masses and the number of atoms. That is, the sodium atom has a total of eleven electrons. Electrons equal to protons are located in a circular shell(orbit) outside the nucleus. That is, the number of protons in the sodium is eleven. The atomic number is the number of protons. Protons and neutrons are located in the nucleus. The nucleus is located in the center of the atom.
