Chapter 12, Problem 126E

(a)

Interpretation Introduction

Interpretation:Name and formula of binary compound formed from $\text{Li}$ and $\text{N}$ should be determined.

Concept introduction:The proportions of atoms in a compound are represented with symbols of element and it is termed as chemical formula. Chemical formula is decided by the valency of the elements. Number of electrons of element in outermost shell is termed as its valency. If number of valenceelectrons is equal to 4 or less than 4 then valency will be valence electrons. For more than 4 valence electrons valency is calculated by subtraction of valence electrons from octet that is 8.
