For example, the electron notation of phosphorus is 1s 2 2s 2 2p 6 3s 2 3p 3, while the noble gas notation is [Ne] 3s 2 3p 3. The next six electrons will go in the 2p orbital. Get step-by-step explanations, verified by experts. Monoatomic cations: Group 1A. © copyright 2003-2021 Study.com. Therefore the Magnesium electron configuration will be 1s 2 2s 2 2p 6 3s 2. {/eq}. 3 Answers. The noble gas is substituted to represent all of the electrons that aren’t valence electrons. In writing the electron configuration for Iron the first two electrons will go in the 1s orbital. The valence shell configuration is therefore 4s^2 3d^7, and the core notation is bb"Co": ["Ar"] 4s^2 3d^7 When a transition metal forms an ion, the s electrons are removed before the d electrons. What is the element, and how many electrons are shown in its electron-dot structure? Main-group atoms generally reach a noble gas configuration in a molecule, obeying the octet rule and similar patterns. This give us the (correct) configuration of: 1s2 2s2 2p6 3s2 3p6 3d10 4s1. Top.
