Valence Electrons- the electrons in the final shell of an atom.

Can you identify how many valence electrons there are on a Bohr Diagram?

It's easy! Just count the number of electrons in the outermost electron shell!  

 

 

 

 

 Answers:

Be: 2 valence electrons.

Al: 3 valence electrons.

Si: 4 valence electrons.

O: 6 valence electrons.

Nice Little Periodic Table :)
