Question

How will you find thw valency of chlorine.​

Answer 1

ANSWER

TO FIND VALENCY OF CHLORINE

the atomic number of chlorine is 17. The chlorine atom has 17 electrons, so its electronic configuration is

K L M

2, 8, 7.

chlorine atom has 7 electrons in its valence shell. A chlorine atom can accept a one more electron to achieve the inert gas electron arrangement, so the valency of chlorine is 1.

Answer 2

ATOMIC NUBER OF CHLORIN IS 17

NOW,

ELECRONIC CONFIGURATION OF 17
K L M

17----- 2,8,7

VALENCY----8-7=1

VALENCY = -1
