Question

state the valency of chloride​

Answer 1

HI HERE IS YOUR ANSWER DEAR.

ATOMIC NUMBER = 17

ELECTRONIC CONFIGURATION

K = 2

L = 8

M = 7

IT NEEDS ONE ELECTRON TO ATTAIN NOBLE GASE CONFIGURATION

THERE ITS VALENCY

= CL^-1

Answer 2

CL is 17 and its electronic configuration is 2,8,7 since it has 7 valence electron in its outermost shell and it needs one electron to complete its state hence its valency is -1
