Periodic TableIonization Energy Exceptions2Choose the best answerBoron has a lower first ionization energy than beryllium because:AA 2p-electron is removed more easily than an electron from a filled 2s-subshell.BAn s-electron is always removed more easily than a p-electron.CIonization energy always decreases with atomic number.DBoron has a completely filled p-subshell.
