Ionization energy (I. E.) is the energy required to remove an electron from a gaseous atom or ion.
• First I.E. corresponds to removing the first valence electron from a neutral atom
• Second I.E. refers to removing a second electron
• Third I.E. refers to removing the third electron
A space probe identifies a new element in a sample collected from an asteroid. Successive ionization energies (in attojoules per atom) for the new element are shown below.
