Answer 1

Answer #1

Answer :

13) The electron configuration of Sr is = Kr [ 5s² ]

So, principle quantum number n = 5,

azimutal quantum number l = 0,

magnetic quantum number m_l = 0.

So, the answer is option C .

Option C is the set of quantum numbers corresponding to one of the valance electrons in Sr.
