While looking at the electronic configuration for an element, it is easy to identify the number of valence electrons.
The electrons that are present in an outermost electron shell for an element are known as valence electrons. They are the electrons withinside the outermost or valence shell, are vital as they offer perception into an element's chemical homes and are those gained, lost, or shared for the duration of a chemical reaction. In general, atoms are maximum solid and least reactive while their outermost electron shell is full. The number of valence electrons in atoms might also additionally purpose them to be unreactive or especially reactive.
