List Of Elements Of The Periodic Table - Sorted By Atomic

Ionization energy (IE): The energy required to remove the outermost electron from an atom or a positive ion in its ground level. The table lists only the first IE in eV units. To convert to kJ/mol multiply by 96.4869. Reference: NIST Reference Table on Ground states and ionization energies for the neutral atoms.IE decreases going down a column of the periodic table, and increases from left to
