PROBLEM 28P

Write a generic Lewis structure for the alkali metals. Do the alkali metals tend to gain or lose electrons in chemical reactions? How many?

Step-by-Step Solution:

Solution 28P

Step 1:

Here, we have to write the generic Lewis structure for the alkali metals and determine if the alkali metals tend to gain or lose electrons in chemical reactions? If so, How many?

A Lewis structure is a graphic representation of the electron distribution around atoms. They illustrate the lone pairs of electrons in molecules. They are also called as Lewis dot diagrams and they are used as a simple way to show the configuration of atoms within a molecule.

The alkali metals are a group (column) in the periodic table consisting of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). They belong to group 1A. The alkali metals are so reactive that they are generally found in nature combined with other elements.

The generic lewis structure of alkali metals is :

All alkali metals have 1 valence electron. Hence the generic lewis structure of alkali metals is :

        

Step 2:

1. Lithium (Li) :

        The lewis structure of Li is :

                        

2. Sodium (Na) :

        The lewis structure of Na is :

                        

3. Potassium (K) :

        The lewis structure of K is :

                        

4. Rubidium (Rb) :

        The lewis structure of Rb is :

                        

5. Caesium (Cs) :

        The lewis structure of Cs is :

                        

6. Francium (Fr) :

        The lewis structure of Fr is :
