       • 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
