electrons
Answer:energy
Explanation:
Energy can be added to an atom to cause a non-valence electron in the atom to temporarily become a valence electron. The correct option is A.
Valence electrons are those electrons that are present in the outermost shell of the atom. These electrons are free to form bonds with another atoms.
Non-valence electrons are preset in the inner shell of the element. These shell are fulfilled with electrons, and these electrons does need to form bonds with other atoms to fulfill their orbit.
The electrons in the orbit have different energies present. The energy change when the electrons transfer from one shell to another shell. When energy is given to the electron, they move to the higher orbit or shell.
Thus, the correct option is A, energy.
