what is the complete electron configuration for the scandium atom

Solutions

Expert Solution

1s2 2s2 2p6 3s2 3p6 4s2 3d1

s orbitals can only hold 2 electrons, p can hold 6, d can hold 10.
Also, electrons almost NEVER move on to the next orbital/energy level without completing the previous one, the exceptions being in elements like chromium where half a filled 3d orbital is stable enough to have only 4s1 (instead of 4s2)
