Question

What is the noble gas notation for chlorine

Answer 1

[Ne] 3s2 3p5

Answer 2

[Ne] 3s^2 3p^5
Knowing that the standard configuration for chlorine is: 1s^2 2s^2 2p^6 3s^2 2p^5
And the configuration of Neon is: 1s^2 2s^2 3p^6
We can replace the first part of the electron configuration with the notation [Ne] then fill in from there.
