Question

which statement is true of the atom shown in the diagram? an electron will move from the outer to the inner shell. the atom is in the excited state. the atom has more than one valence electron. all of the above. none of the above.

Explanation:

If an electron is in a higher - energy outer shell and can move to a lower - energy inner shell, it will do so to reach a more stable state. An atom with an electron in a higher - than - normal energy level is in an excited state. Valence electrons are the electrons in the outermost shell, and from the diagram, it seems there are multiple electrons in the outer shell.

Answer:

D. All of the above
