The long electron configuration of darmstadtium is:1s22s22p63s23p63d104s24p64d104f145s25p65d105f146s26p66d87s2
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
Long-hand version: 1s^2 2s^1 Short-hand version: [He] 2s^1 Note: The "^" symbol means the the following number is in the form of a superscript.
Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1 3d^5 Short-hand version: [Ar] 4s^2 3d^4 Note: The "^" symbol means the the following number is in the form of a superscript. The above is wrong because Cr is an exception. the actual answer is [Ar] 4s^1 3d^5 because it has a half filled subshell
Long-hand version: 1s^2 2s^2 2p^4 Short-hand version: [He] 2s^2 2p^4 Note: The "^" symbol means the the following number is in the form of a superscript.
