Question

Draw Lewis stucture for the
compounds formed by the following pairs of the elements-
(a) Na and S
(b) Ca and N​

Answer 1

Answer:

By the end of this section, you will be able to:

Write Lewis symbols for neutral atoms and ions

Draw Lewis structures depicting the bonding in simple molecules

Thus far in this chapter, we have discussed the various types of bonds that form between atoms and/or ions. In all cases, these bonds involve the sharing or transfer of valence shell electrons between atoms. In this section, we will explore the typical method for depicting valence shell electrons and chemical bonds, namely Lewis symbols and Lewis structures.

LEWIS SYMBOLS

We use Lewis symbols to describe valence electron configurations of atoms and monatomic ions. A Lewis symbol consists of an elemental symbol surrounded by one dot for each of its valence electrons:

A Lewis structure of calcium is shown. A lone pair of electrons are shown to the right of the symbol.
