Question

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

Explanation:

Electron dot diagrams (Lewis dot structures) are simplified representations that focus only on the outermost electrons of an atom, which are the valence electrons. They do not show electron shells or electrons in inner shells.

Answer:

the number of valence electrons an atom has
