Question

Which of the following do Lewis structures help us understand?

the exact structure of a molecule
the number of electrons that are involved in the bonding of the molecule
the total number of electrons in a molecule
how electrons attract other electrons in a molecule

Answer 1

Answer: Option (b) is the correct answer.

Step-by-step explanation:

A diagram which shows the number of electrons involved in bonding and number of lone pairs present on the atom(s) is known as a lewis structure.

The electrons in lewis structure are represented by dots.

Therefore, we can conclude that Lewis structures help us understand the number of electrons that are involved in the bonding of the molecule.

Answer 2

The correct answer is this one: "the number of electrons that are involved in the bonding of the molecule."  Lewis structures help us understand the number of electrons that are involved in the bonding of the molecule. It also helps us know the shape of the molecule, its reactivity and its interaction with other molecules.
