Question

What will be the Atomic number of an element in which the electrons are occupying 3 shells, and the
valence shell has 4 electrons? (Show steps to get the answer)

Answer 1

Answer:

atomic number will be 14

Explanation:

If it occupies three shells then :

first shell will have two electrons (will usually have two electrons)

second shell will have eight electrons.

(if it is occupying three shells then second shell. will have eight electrons )

third shell will have four electrons(as mentioned in the question)

third shell is the valence shell

electronic configuration=2,8,4

K=2

L=8

M=4
