Concept explainers
Refer to the group numbers of the periodic table and draw Lewis structures for atoms of the following:
a. potassium
b. barium
c. aluminum
d. bromine
(a)
Interpretation:
Lewis dot structure of the potassiumis to be drawn.
Concept introduction:
Lewis structure is a representation of a chemical formula of substance with valance electrons of atoms. The Lewis structures are also called electron dot structures. In the Lewis structure, electrons are denoted by dots. Only the valence electrons are presented as dots in the Lewis structure.
Answer to Problem 4.1E
