Energy is conserved.
A photon has energy. For this reason, TiO molecules form and survive in reasonable numbers only in cool stellar atmospheres. A neutral atom of a given element has an electron cloud containing electrons equal in number to the number of protons in its central nucleus. Recall that it is the number of protons that defines the element in question. A positive ion of the same element is an atom with one or more fewer electrons than protons.
