* Configurations of elements 103 and 104 are uncertain; those for elements 105 and above are not available. Predictions from reliable sources have been used for these elements. * Grayed out electron numbers indicate subshells that are filled to their maximum. * The bracketed noble gas symbols on the left represent the inner configurations that are the same in each period. Written out these are: :: He, 2, helium : 1s2 :: Ne, 10, neon : 1s2 2s2 2p6 :: Ar, 18, argon : 1s2 2s2 2p6 3s2 3p6 :: Kr, 36, krypton : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 :: Xe, 54, xenon : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 :: Rn, 86, radon : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 :: Uuo, 118, ununoctium : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6 * ''Note the non-linear shell ordering, which comes about due to the different energies of smaller and larger shells.'' == References == *Electron configurations of the elements (data page) 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Periodic table (electron configurations)」の詳細全文を読む スポンサード リンク
