Interpretation:
A Lewis dot structure and its creation need to be explained.
Concept introduction:
Lewis dot structure is used to represent the structure of a molecule in which valence electrons of all atoms are shown.

Answer to Problem 2E
A Lewis dot structure is the representation of a molecule showing valence electrons of atoms which includes both bond pair electrons along with lone pair electrons.
Explanation of Solution
For drawing a Lewis dot structure the number of valence electrons of all the atoms forming the molecule must be known. After making the bonds within the molecule extra electrons are shown as dots on the atoms which are known as lone pairs of electrons. The Lewis dot structure of water molecule is shown below as an example.
