Number Of Electrons In Sodium
Click here π to get an answer to your question οΈ How many electrons are in an atom of elemental sodium? Equal to the number of neutrons equal to the number of kjguydgv4 kjguydgv4. Each electron has a charge of 1, and each proton has a charge of 1+. You can calculate the charge of an atom by subtracting the number of electrons from the number of protons. Move an electron from the sodium to the chlorine atom. What are the charges of each atom now? Sodium, with a total of 11 electrons, has only one electron in its third and outermost shell.

 The number of electrons in an electricallyneutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Sodium is 11. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z β 1) negative electrons in the atom.

Number Of Electrons In Sodium Cation
Na is a monovalent metal (BCC) with a density of 0.9712 g cm^{3}. Its atomic mass is 22.99 g mol^{1}. The drift mobility of electrons in Na is 53 cm^{2}(Vs)^{1}.

 22.99 g = 6.023 x 10^{23} atoms
so, in 0.9712 g of Na we have = (6.023 x 10^{23} x 0.9712)/22.99 = 2.544 x 10^{22} atoms.
It means 1 cm^{3} has 2.544 x 10^{22} atoms.
Since, each Na atom contributes one electron, the total number of electrons in 1 cm^{3} (n) = 2.544 x 10^{22} electrons.
Given that the particles's mean separation d = 1/n^{1/3} (it should be noted that it is an approximation)
Plugging the value of n gives d = 3.4 x 10^{8} cm or 0.34 nm.  The crystal structure of sodium is BCC (body centered cubic), which has 2 sodium atoms per unit cell (one at the center and one shared by eight corners). The figure below shows the (110) plane of a sodium unit cell.
If a is the lattice parameter (size of the unit cell) and R is the radius of the atom, then the relation between them is:
