The Lewis dot model of an atom has three dots. The statement that is true about the atom is it has three valence electrons. The correct option is A.
Lewis dot model or Lewis structure is a method that was given by Gilbert N. Lewis. It was introduced in 1963. The model is made to put dots around the elements. These dots show the valence electron of the atoms. The model was extended by putting lines around the element.
If an atom has three dots around us, it means the element has three valence electrons. The element is lithium. Lithium has three electrons that are lone or valence, which means it can share and donate three electrons.
Thus, the correct option is A. It has three valence electrons regarding true about the atom.
