If you flip the Periodic Table over you will have the ionization energy of sodium, first ionization energy, 5eV and it is about 5 eV which, when you convert, 496kJ/mol is a whopping 496 kilojoules per mole.
如果浏览周期表,你可以得到钠的离子化能,第一电离能,大约,当你转换的时候,是巨大的。

69KJ/moL Somewhere here, 569 over here, kilojoules per mole, 608 and by his formula he gets 608, which isn't bad, which really isn't bad at all.
