PPT-What causes reactivity of elements

All atoms want to have a completely full valence shell normally 8 electrons For the moment we will only concentrate on main group elements Noble gases are already full Elements that are really close desperately want to get there halogens and alkali and tend to be the most reactive.

(Below left) A sample report screen displays a right finger temperature curve (red), a left finger temperature curve (blue), and a Zero Reactivity Curve (green).. What is an element?. A element is a pure substance made of one type of atom. Elements are divided into metals and non-metals. Examples of non-metal elements include carbon, oxygen, hydrogen, and nitrogen. All atoms want to have a completely full valence shell (normally 8 electrons).. For the moment we will only concentrate on main group elements. Noble gases are already full..
