Express the complete electron configuration using superscripts where appropriate

Question

Express the complete electron configuration using superscripts where appropriate. For example, the configuration for Li would be entered as 1s Give the ground state electron configuration for silicon (Si) noble-gas shorthand. Express your answer in condensed form as a series of orbitals. For example [Ar]4s^23d^5 would be entered as Give the actual ground state electron configuration tor copper (Cu) using the complete form Express the electron configuration using superscripts where appropriate. For example, the configuration for Li would be entered as

Explanation / Answer

Part B

Electronic configuration of Si in noble gas shorthand is [Ne] 3s2 3p2 . In this method, the noble gas which is coming prior to this element in the periodic table is used.

Atomic number of Si is 14, and the noble gas coming just before Si is Ne (atomic number 10)

Part C

Atomic number of copper is 29

electronic configuration is

1s2 2s2 2p6 3s2 3p2 3d104s1

Due to high stability of d10 configuration, 4s orbital occupy as singly occupied

Part C

in noble gas shorthand form, the electronic configuration of copper is [Ar] 3d10 4s1

Ar is the filled noble gas before copper
