Question

Read the following passage carefully and answer the question that follows: An ionic or electrovalent compound is a compound in which ions are held together by ionic bonds. An ionic bond is the type of chemical bond in which oppositely charged ions (cations and anions) are held together through strong electrostatic forces. We know that metal atoms are electropositive and hence, they have a tendency to lose their valence electrons and form cations to attain noble gas configuration. On the other hand, non-metal atoms are electronegative and hence, they have a tendency to gain electrons and form anions to attain noble gas configuration.
Q1: Which of the following pairs of elements will form an ionic bond?
Ca and Mg
Mg and Cl
Zn and Fe
Fe and Na​

Explanation:

Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion). A brief treatment of ionic bonds follows. For full treatment, see chemical bonding: The formation of ionic

bonds.
