Question

Predict the type of bond that would be formed between each of the following pairs of atoms(ionic, polar covalent or nonpolar covalent)
a. H and Cl
b. Mg and F
c. Li and N
d. N and S

Answer 1

Answer:

In between H and Cl the bond will be covalent.

In between Mg and F the bond will be ionic.

In between Li and N the bond will be ionic .

In between N and S the bond will be polar covalent.

Explanation:

Ionic bonds are defined as the bonds which are formed by the complete transfer of electrons from cation (positively charged ions) to anion (negatively charged ions). For Example: NaCl, $MgF_2$ etc.

Covalent bond is defined as the bond which is formed by the sharing of electrons between the atoms. For Example: HCl, $CH_4$ etc.

Its of two type:

• Polar covalent compound: This compound is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example: $CO_2,NO_2$ etc..
• Non-polar covalent compound: This compound is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: $N_2,O_2$ etc.

In between H and Cl the bond will be covalent.

In between Mg and F the bond will be ionic.

In between Li and N the bond will be ionic .

In between N and S the bond will be polar covalent.
