Reactivity, Electron Configuration, & Valence electrons:
· Valence electrons-The electrons in the last energy level in an atom.
· Increase in number as you go across the period but starts back at one when you go to a new period. So the valence electrons stay the same as you go up or down but increase from left to right.
· Reactivity- The reactivity is based on the position of the elements on the periodic table. It depends on how far down the

Electron Configuration
· The electron configuration is the specific way to locate elements on the periodic table by classifying it by the amount of electrons.
