The least ionic type of bond is a covalent bond.
Na and Cl, Mg and O
Generally, if the difference of electronegativity between the two elements are less than 1.7 according to Pauling's scale, they form a covalent bond or otherwise an ionic bond. Although there are exceptions such as hydrogen fluoride (which is covalent but the electronegativity difference is 1.9 approximately).
Only sodium and chlorine will form ionic bond. the other pair given here will form covalent bond

covalent bond
Ionic bond exist between metals and nonmetals.
The pair of electrons is shared to form a covalent bond.
Group 1 or group 2 elements with group 16 or group 17 elements. In general, if the electronegativity difference between the two atoms is more than 1.7 in Pauling's scale, then the two atoms form ionic bond.

Each atom only donates ONE atom, so they form a pair together.
A metal tends to form an ionic bond with a non-metal. Metals bonding with other metals form a metallic bond, and non-metals bonding with other non-metals form a covalent bond.
