Chapter 21, Problem 60PS

Interpretation Introduction

Interpretation: To predict the statement which is incorrect for ammonia.

Concept introduction: Nitrogen belongs to group $\text{5A}$ of the periodic table. The electronic configuration of nitrogen is $\left[\text{He}\right]{\text{2s}}^{\text{2}}{\text{2p}}^{\text{3}}$. Nitrogen gains three electrons in the outermost shell and has $-3$ oxidation number. Hydrogen is less electronegative as compared to nitrogen. Hydrogen bears positive charge and nitrogen is negatively charged in molecular compounds. The charge on nitrogen is $-3$ and the charge on hydrogen is $+1$ A molecular compound by direct combination of hydrogen with nitrogen formed is ${\text{NH}}_{\text{3}}$. This compound is ammonia.
