ent topics, but they followed similar steps to complete their lab investigations. Even though they are studying different subjects, Jon and Katarina use the same method for completing a lab report because they are both
The first ionization energy is the energy that the atom lost its first electrons. The energy decrease and the atom is more reactive. So from highest to lowest is Li>Na>K>Rb.
