Explain in the normal hydrogen atom the electron is in its lowest energy state, which is called the ground state of the atom. Define the maximum electronic energy that a hydrogen atom can have is 0 KJ/mole at which point the electron would essentially be removed from the atom also it would become a H+ ion. Define how much energy is kilojoules per mole does it take to ionize an H atom?
Define the ionization energy of hydrogen is often expressed in units other than KJ/mole. Explain what would it be in joules per atom in electron volts per atom? (1cv=1.602o10-19).
