Which element has a neon core and five valence electrons in its ground state electron configuration?

Which element has a neon core and five valence electrons in its ground state electron configuration?


Solutions

Expert Solution

The electronic configuration of Chlorine is [Ne]3s23p5 so it has seven balance electrons so it cannot be the answer.

Answer is phosphorous who has Ne core and balance elctrons are five [Ne]3s23p3.

So answer is P i.e phosphorous
