Difference between Na and Na+ (Sodium atom vs Sodium ion)

Sodium (Na) and sodium ion (Na+) are related to each other but have different chemical properties. This is because Na+ has lost a valence electron.
Sodium (Na):
Sodium is a chemical element with the atomic number 11, which means it has 11 protons in its nucleus.
Sodium in its elemental form (like on the Periodic Table) has one valence electron in its outermost electron shell.
Sodium is highly reactive and is known for its tendency to lose that single valence electron in chemical reactions. When it loses the negatively charged electron the overall charge for the Sodium ion is now 1+.
Sodium Ion (Na+):
A sodium ion, Na+, is the result of sodium losing its single valence electron to achieve a stable electron configuration.
It has 10 electrons, as it has one fewer electron than the neutral sodium atom.
The loss of the electron gives the sodium ion a positive charge (cation).
The positive charge is because the number of protons (11) in the nucleus is greater than the number of electrons (10) surrounding it.
Sodium ions are much less reactive than neutral sodium atoms. They are stable and do not readily participate in chemical reactions like sodium metal does.

Cations in general have a smaller atomic radius than their neutral counterparts as the greater positive attraction in the cation draws the electron cloud “closer to the nucleus” 👍🏻

Sir why na+ has 1 valency either having 10 Electron
