Respuesta :

Boron is in the third group, so it has 3 valence electrons. Therefore, it has 3 valence electrons. 

Answer:

3 dots.

Explanation:

The answer is 3 dots. We can use boron's position within the periodic table to help us figure this out. When looking at the periodic table, we see that boron is in group 3. The group number corresponds to the number of valence electrons that an element has. Therefore, boron has 3 valence electrons and will need to show all of these 3 electrons in its Lewis dot diagram.
