Question

The electron configuration for an element in the halogen group should always end with Question 16 options:

ns2np6
ns2np5
ns2np4
ns2np2?

Answer 1

ns²np⁵

Step-by-step explanation:

The electronic configuration of elements of halogen group ends with 7 electrons in its outer most shell and they distributed as ns²np⁵.

Such as Cl (17 electron): 2,8,7 which is 1s²2s²2p⁶3s²3p⁵.
