The lewis dot model of an atom has three dots. which of the following statements is true about the atom?

it has three valence electrons.
it has three innermost shell electrons.
it has three energy levels.
it has three subshells.

The answer to your question is It has three valence electrons.

Explanation:

It has three valence electrons.  The Lewis dot model considers only the valence electrons to represent the electrons that interact with another molecule, so it a model has three dots these dots are the valence electrons.

It has three innermost shell electrons.  Innermost shell electrons are not considered in the Lewis dot model, if it would consider them, these must be only 2, not three.

It has three energy levels.  Elements that are located in group 3 have three valence electrons, elements that have three energy levels are located in period three and not all of them have three valence electrons.

It has three subshells. This option is incorrect.
