Question

Write down the electronic configuration of k+ and cl-

Answer 1

ANSWER
__________________________

ELECTRONIC CONFIGURATION :

K has atomic no. 19
Conf. = 2,8,8,1
But here it is K+ i.e. k ion with one electron donated

K+ = 2,8,8

____________________________

Cl has atomic no. 17
Conf. = 2,8,7
But here it is Cl- i.e. Cl ion with one electron accepted

Cl- = 2,8,8

Answer 2

no..of electron in k= 19
no..of electron in k+ = 18
electronic configuration of k+ is in image
In k+ electronic configuration is 1s2 ,2s2 ,2p6, 3s2 3p6

no..of electron in cl = 17
no..of electron in cl- = 18
electric configuration is
