An orbital-filling diagram shows the number of electrons m each orbital, which are shown in order of energy. The placement of electrons in orbitals follows a certain set of rules. Lower energy subshells fill before higher energy subshells. The order of filling is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. The periodic table can be used to help you remember this order. An orbital can hold up to...
