Question

Na+ as completely filled first 2 cells.explain ??​

Answer 1

Answer:

Na ( sodium )

Explanation:

it's electronic configuration is = 2,8,1

because its atomic no. is 11

it has two complete shells as its K and L shells are complete ( it's duplet and octate )

Answer 2

Hey mate ,

Na+

Its electronic configuration is 2, 8, 1. But, Na+ ion has one electron less than Na atom i.e. it has 10 electrons. Therefore, 2 electrons go to K-shell and 8 electrons go to L-electrons, thereby completely filling K and L shells.
