Question

Find out all the quantum numbers of last electron of fluorine​

Answer 1

Answer:

fluorine :

atomic number : 9

electronic configuration: 2,7

there are 7 electrons in outermost orbit

hence it need 1 electron to complete its octet

therefore valency : 1

Answer 2

Explanation:

The electronic configuration of fluroine is :-

The number of electrons on fluroine is 9 -

K L M N

2 7

Therefore the valence electrons are 7 and valency is 1 .
