Neon Electron Configuration and Valence Electrons

This video tutorial explains how to determine the number of valence electrons for the element neon. It covers two methods: using the periodic table and examining the electron configuration. Neon, found in group 18 of the periodic table, has eight valence electrons. The video also details the electron configuration method, showing that neon's atomic number is ten, with a full 1s2, 2s2, and 2p6 configuration, confirming the eight valence electrons. The tutorial concludes by summarizing these findings.
