Si Electron Configuration - BRAINGITH

WebAug 4, 2024 · The first ten electrons of the sodium atom are the inner-shell electrons and the configuration of just those ten electrons is exactly the same as the configuration of the element neon \(\left( Z=10 \right)\). This provides the basis for a shorthand notation for electron configurations called the noble gas configuration. WebSilicon (Si) has an atomic number of 14. This means it contains fourteen electrons. It belongs to Period 3 and Group 14 (4A). The expected electron configuration of Si is. 1s 2 2s 2 2p 6 3s 2 3p 2 \begin{aligned} \text{1s$^2$2s$^2$2p$^6$3s$^2$3p$^2$} \end{aligned} 1s 2 2s 2 2p 6 3s 2 3p 2 dekalb county dmv fort payne al
