Question

what helps in determining the formula of an ionic compound?

Answer 1

In chemistry, an ionic compound is a chemical compound composed of ions held ... Principal contributors to the development of a theoretical treatment of ionic crystal structures were ...

Answer 2

hey mate!!

the valency i.e the shells in the outer most shells of electrons help in determining the formula of an ionic compound .

for example, ws have to make magbesium chloride

magnesium has 12 valence elctrons =2,8,2 , thus its valency is 2

chlorine has 17 valence elctrons=2,8,7 , thus its valency is 3

now , in magnesium chloride , we will share 1 electron each with 2 atoms chlorine to full their valence shell , thus the compound become mgcl2


hope it helped!!
