The Electron Configuration: Condensed Video Lessons

Concept:

# Problem: Give the ground-state electron configuration for silicon (Si) using noble-gas shorthand. Express your answer in condensed form as a series of orbitals. For example, [Ar]4s23d8 would be entered as [Ar]4s23d8.An atom consists of a small, positively charged nucleus, surrounded by negatively charged electrons. We organize the electrons in a logical manner. As the atomic number increases, electrons are added to the subshells according to their energy. 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.
