Answer :
Atom of sodium has 11 protons, 12 neutrons, and 11 electrons outside of it. One of the many atoms that can readily transfer an electron is sodium.
The element with 11 protons and 12 neutrons has an atomic number of 23.
The sodium valence electron is +1.
Protons and neutrons combined make up an atom's atomic mass.
Atomic mass is calculated as follows: 11 + 12 = 23 protons + neutrons
Lithium, sodium, potassium, and other elements in the first column of the Periodic Table all have one electron in the outer electron shell. This indicates that they have comparable qualities and act similarly in chemical processes.
