what is the electronuc conjiguration of na -​

Answer 1

$\huge\star{\pink{\underline{\mathfrak{answer}}}}$

[Ne] 3s¹

In this notation, the electronic configuration of sodium would be 1s22s22p63s1, distributed in the orbitals as 2-8-1. Often, a shorthand method is used that lists only those electrons in excess of the noble gas configuration immediately preceding the atom in the periodic table.
