For each ionic compound,the main group to which X belongs the charge of SO4 is 2-, so the charge of (SO4)3 is 6-. The charge of X2 is 6+, so the charge of X is 3+, so group 3A.
The charge of SO4 is 2-, so the charge of (SO4)3 is 6-. The charge of X2 is 6+, so the charge of X is 3+. We conclude from the formula that X must be a donor of electrons and that it must donate three electrons. x is a member of group 3 A.
What is the formation of ionic character?
A polar covalent bond's degree of charge separation is referred to as its ionic nature. Finding the difference between the two atoms' electronegativity is helpful.
Δχ = χB − χA
Bond polarity and ionic nature grow as the difference in electronegativity widens.
