Question

How many electrons with l=2 are there in an atom with Z=54? (Need explanation)

Answer 1

Answer:

27

Explanation:

z=54/2=27, 27 electrons with L=2 are there in an atom withZ=54

Answer 2

Answer:

When we say l =2 it means we are talking about d subshell.

S=0

P=1

D=2

F=3

Here the atomic number is 54 so the configuration is:

[Ar] 3p6 3d10 4s2

D= 10

Hence 10×2=20
