Answer 2

Answer:

W-lithium{Li}

X-fluorine {F}

Y-silicon {Si}

Z-argon{Ar}

Only lithium and fluorine combine to form ionic compound.

Explanation:

Ionic compounds are formed when an element carrying negative charge and an element carrying positive combines to form compound.

For e.g. Sodium carrying positive charge combines with chloride carrying negative charge to form sodium chloride.

Lithium{Li⁺} combines with bromide{Br⁻} to form lithium bromide{LiBr}.
