1. What are materials made of ?

   • all materials are made up if atoms
     • and the substance made up of only one atom is called an element
       • all did you know that there are over 100 different elements like sulfur or copper.
   • But when you add two or more element together . It will make a Compound
   • in the center of an atom there is a
     • Nucleus which is the contral of the atom
       • with the Nuclesus there is a proton and neutrons. also there is a electrons outside the nucleus
         • The proton is +1
         • the neutronos 0 (neutral)
         • the electron is -1

2. electrons rule chemistry

   • electrons are shared to make bond within a moelcules
   • when they share bond they always have to have a balanced equation
   • The group 0 they do not have to share only bond becaues they already have 8 atoms alos they there unreactive
