Question: what is electron configuration examples?
Answer: An electron configuration lists only the first two quantum numbers, n and ℓ, and then shows how many electrons exist in each orbital. For example, write the electron configuration of scandium, Sc: 1s2 2s2 2p6 3s2 3p6 4s2 3d1 . ... This is a memory device to remember the order of orbitals for the first two quantum numbers.
