Concept Introduction:
Law of conservation of mass states that the mass of products and reactants always remains constant during a chemical reaction.
Law of conservation of energy is defined as the basic law that energy can never be created and never be destroyed.
The change in mass and energy is given by the equation as follows:

The Helium Ion, Het, has energy levels similar to those of the hydrogen atom. The helium ion, like the hydrogen atom, has only one electron. This eliminates electron-electron interactions, and allows us to calculate the energies of the electron in each of the energy levels (n = 1, 2, 3 .) of the helium ion:
