which is a model that shows only the valence electrons of an atom?

The electrons in the outermost shell, or energy level, of an atom are Valence electrons. Electron dot model is a model that shows only the valence electrons of an atom, i.e., option C.
Because valence electrons are so crucial, atoms are frequently represented by simple diagrams that only show their valence electrons.
These are known as electron dot diagrams. Also referred to as Lewis structures.
Electron dot model is a model that shows only the valence electrons of an atom.
Thusm the correct option is C.
