Question

How will you findthe valency of chlorine, sulphur and magnesium ?​

Answer 1

hey mate!

here is ur ans...

>> If the number of electrons in the outermost shell of the atom of an element is less than or equal to 4, then the valency of the element is equal to the number of electrons in the outermost shell. ... The distribution of electrons in chlorine, sulphur, and magnesium atoms are 2, 8, 7; 2, 8, 6 and 2, 8, 2 respectively.

hope it helps....❤❤

Answer 2

Answer:

valency of chlorine is -1

valency of sulphur is -2

valency of magnesium is +2

Explanation:

chlorine has 7 electrons in its outermost shell so it gains 1 electron to attain the nearest noble gas configuration

similarly sulphur gains two electrons as it has 6 electrons in its outermost shell

on the other hand magnesium loses 2 electrons as it has 2 electrons in its outermost shell so it's valency is +2

If an element gains electrons then the valency is negative and if it donates electrons then valency is positive
