What is the relationship between an elements number of valence electrons and its electron configuration?
As the valence electrons fills the outer shell, it also fills the subsequent shells in the electron configuration. Each Valence electron helps to fill up the Electron configuration shells and the valence electrons helps to determine which shell to fill up. There’s a more scientific term that i don’t know about but if anyone can add on to this that would be great since i’m just starting in Chemisrty.
