Give the ground-state electron configuration for silicon (SiSi) using noble-gas shorthand. For example, [Ar]4s23d8[Ar]4s23d8 would be entered as [Ar]4s^23d^8. Give the ground-state electron configuration for copper (Cu) using noble-gas shorthand. For example, [Ar]4s23d8 would be entered as [Ar]4s 23d 8.
The electron configuration of the carbon atom represented by the orbital is
C = 1s 2s 2p
This electron configuration can be written as
1s2 2s2 2p2
where 1s, 2s. and 2p are the occupied subshells, and the superscript "2" is the number of electrons in each of these subshells. Use the rules for determining electron configurations to write the electron configuration for Ca.
