Chapter 4.6, Problem 1QQ

Interpretation Introduction

Interpretation:

Among the given options the number of electrons oxygen atom, acquire via electron transfer for formation of ionic compound ${\text{K}}_{\text{2}}\text{O}$ has to be chosen.

Concept Introduction:

Ions are formed by the loss or gain of electrons.  The formation of ion requires the presence of two elements, these two elements are: one is metal atom and another one is non-metal atom.  Metal atom loses electron and non-metal atom accepts electron.  A Lewis structure explains the formation of simple ionic compounds.  A Lewis structure is a combination of Lewis symbols that represents either the transfer or the sharing of electrons in chemical bonds.
