Question

describing electron dot diagrams
what information is shown in an atoms electron dot diagram?
the number of shells an atom has
the number of electrons in each shell of an atom
the number of valence electrons an atom has
the number of valence shells of an atom

Explanation:

An atom's electron dot diagram (Lewis dot structure) represents valence electrons—electrons in the outermost shell—using dots around the element symbol. It does not show total shells, electrons per shell, or valence shell count.

Answer:

the number of valence electrons an atom has
