For each ionic compound formula, identify the main group to which X belongs: (c) X2SO4.
Zinaida [17]

The answer is group 1A.

In the ionic compound formula X₂SO₄, SO₄ has a -2 charge. Hence to balance this -2 charge of SO₄, X must have a +1 charge.

Group 1A elements form X⁺ type of ions because they are metals. So, they have the tendency to lose electrons.

Hence, X must belong to the 1A group.

Ionic Compounds-

  • Ionic compounds are formed by the electrostatic attraction between the anions and the cations.
  • Cations are positively charged ions that are formed due to the loss of electrons.
  • And the anions are negatively charged ions that are formed due to the gain of electrons.
  • Due to this, they have opposite charges and form bonds known as Ionic Bond.
