Answer:
the valency of chlorine = 1
the valency of sulphur is = 2
the valency of magnesium = 2
we can find valency by charge present on them
pls mark as brainliest and follow
Explanation:
The electronic configuration of chlorine is =2,8,7
Since, chlorine has 7 (more than 4) electrons in its outermost shell
valency of chlorine = 8- number of electrons in outermost shell
= 8-7
= 1
The electronic configuration of sulphur is = 2,8,6
valency of sulphur = 8- number of electrons in outermost shell
= 8- 6
= 2
The electronic configuration of magnesium is = 2,8,2
Valency of magnesium = 8- number of electrons in outermost shell
= 8-6
=2
Therefore, The valency of chlorine is 1
The valency of sulphur is 2
The valency of magnesium is 2
