WebJan 30, 2024 · In the whole of period 2, the outer electrons are in 2-level orbitals - 2s or 2p. These are all the same sort of distances from the nucleus, and are screened by the same 1s 2 electrons. The major difference is the increasing number of protons in the nucleus as … Web74K views 2 years ago A Level Chemistry Atomic Structure In this video, we look at how first ionisation energy varies across period 2. We explore the reasons for the general increase in...
