   19 wrz 2024 · The ground state electron configuration of calcium is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2. This electron configuration shows that the last shell of the calcium atom has two electrons. When calcium atoms are excited, then calcium atoms absorb energy. As a result, an electron in the 4s orbital jumps to the 4p x orbital.
