Detailed explanation-1: -The tendency is for sodium to lose an electron so that the new resulting valence shell (2) is in its most stable state (full octet). This loss of an electron results in the ionization of sodium, to form the positively charged ion Na+.
Detailed explanation-2: -Na → Na + + e-( Sodium ) ( Sodium cation ) ( 2, 8, 1 ) ( 2, 8 ) To complete its octet, sodium loses an electron from its outermost shell. The electronic configuration becomes 2, 8. As there are 8 electrons in the valence shell, therefore it attains stability according to the octet rule.
Detailed explanation-3: -Sodium would become stable if it could lose an electron and attain the configuration of neon (2, 8). Every atom has the tendency to acquire the configuration of the nearest noble gas and become stable.
Detailed explanation-4: -Some atoms become more stable by gaining or losing an entire electron (or several electrons). When they do so, atoms form ions, or charged particles. Electron gain or loss can give an atom a filled outermost electron shell and make it energetically more stable.
