An electron moved from a higher energy level to a lower energy level. What most likely happened during the transition? A photon was released.
A photon was absorbed.
A fixed amount of energy was absorbed.
A random amount of energy was released.

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
