Chapter 11, Problem 87AE

(a)

Interpretation Introduction

Interpretation:

The given compound $N{a}_{3}P$ has to be identified whether it is ionic compound, covalent compounds or both.

Concept Introduction:

An electronegativity of an atom gives information about the strength that the atom has for attracting a pair of shared electrons.  The greater the attraction for a pair of shared electrons when the electronegativity value is high.  Consequently, when two different electronegative atoms share a pair of electrons, one atom becomes partially positive and the other atom becomes partially negative due to the attractive forces for the pair of electrons.

If the difference in electronegativity is more than $2.0$, the bond will be ionic and if difference in electronegativity is less than $1.5$, the bond will be strongly covalent.
