Question
Chapter 1.3, Problem 6P
Interpretation Introduction
Interpretation:
Lewis formulas for the given molecules are to be drawn, and all the unshared pairs of electrons are to be shown.
Concept introduction:
The total number of valence electrons based on the molecular formula are first determined.
Bonded atoms are connected by a shared electron pair shown by a dash.
The number of electrons in the bonds is subtracted from the total number of valence electrons. This gives the number of electrons that remain to be added.
Electrons are added as unshared electron pairs so that the most electronegative atoms have eight electrons around them.
Second-row elements cannot have more than eight valence electrons.

- 3-37 Answer true or false. (a) An ionic bond is formed by the combination of positive and negative ions. (b) An ionic bond between two atoms forms by the transfer of one or more valence electrons from the atom of higher electronegativity to the atom of lower electronegativity. (c) As a rough guideline, we say that an ionic bond will form if the difference in electronegativity between two atoms is approximately 1.9 or greater. (d) In forming NaCl from sodium and chlorine atoms, one electron is transferred from the valence shell of sodium to the valence shell of chlorine. (e) The formula of sodium sulfide is Na2S.
