Which element has the following electron configuration: 1S₂ 2S₂ 2p6 3S₂ 3p6 4S₂ 3d10?

Question

Quizplus · Accepted Answer

This electron configuration corresponds to the element zinc (Zn) which has 30 electrons. The numbers in the electron configuration indicate the number of electrons in each orbital. The 1s subshell can hold up to 2 electrons, and the 2s and 2p subshells can hold up to 8 electrons each. The 3s subshell can hold up to 2 electrons, and the 3p subshell can hold up to 6 electrons. The 4s subshell can hold up to 2 electrons, and the 3d subshell can hold up to 10 electrons. Therefore, the electron configuration of zinc is: 1s2 2s2 2p6 3s2 3p6 4s2 3d10.
