Question

Na+ has completely filled K and L shells. explain​

Answer 1

Atomic number of Na is 11

Atomic number of Na+ is 10

so electronic configuration is 2,8

That's why K and L shell is completely filled

Answer 2

Answer:

k shell have 2 and l shell have 8

Explanation:

Therefore, the K shell, which contains only an s subshell, can hold up to 2 electrons; the L shell, which contains an s and a p, can hold up to 2 + 6 = 8 electrons, and so forth; in general, the nth shell can hold up to 2n2 electrons. so na+ consists 10 electrons so k as 2 l as 8 .

2+8=10
