To determine the valence electrons in an atom, you write the electron configuration of the element in noble-gas-inner-core form. The electrons outside... Learn more about this topic: Valence Electron | Definition, Configuration & Examples ...
Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus. Valence electrons are of crucial importance because they lend deep insight into an element’s chemical properties: whether it is electronegative or electropositive in nature, or they indicate the...
- The presence of only one electron in the outermost shell makes them highly reactive, as they tend to lose that one electron easily to achieve a stable electronic configuration (like that of noble gases). - The group number in the periodic table corresponds to the number of electrons in th...

For example, take a look at chlorine again. It has 17 electrons. How many are in the valence? The first two levels will be full with 10 electrons. That means there are seven electrons left in the valence shell. This means that chlorine wants to gain an electron in order to have a co...
