what is the valency of chlorinesulphur magnesium |
Answer» <p>The electronic configuration of chlorine can be written as 2, 8, 7. 2, 8, 7 electrons are distributed in the shells K, L, M respectively. Therefore, valence electron in chlorine is 7 and it needs to gain 1 electron from the outermost orbit to attain octet. Hence, the valency of chlorine is 1.</p><p>Similarly, valency of sulphur will be 2. it's electric configuration-- 2,8,6. so,sulphur needs 2 more electrons to complete it's outermost shell.</p><p>By same process valency of magnesium is 2</p> | |
