- - - - Electrons move outside of the nucleus at a very high speed
        
        They can not run away from the nucleus because there is an attraction between equally strong negative and positive charges. As positively charged protons keep them pulled towards then.
  - - - The total negative charge of electrons equals the positive charge of the nucleus. Atoms are neutral.
        
        Positive charge of the protons is is neutralized by the negative charge of the electrons.
  - - - Carry a positive electric charge.
    - - Do not carry any electrical charge.
    - - Negatively charged.
        
        Orbit around the nucleus.
- - - - It can not be divided further or cut further.
- - - - The first shell can have 2 electrons, the second shell can have eight electrons, the Third can hold eighteen, and the fourth can hold thirty-two.
  - - - Atoms always keep trying to fill their shell.
        
        For example, an oxygen atom. In its second shell it can hold up to eight electrons, but the oxygen atom only has six electrons in its second shell, so it is always looking for more electrons to fill its shell. Now a hydrogen atom it only has one electron in its outer shell, but it can hold 2 electrons in its shell, so it is also looking for more electrons. The oxygen atom binds with two hydrogen atoms to fill its valence shell, sharing one electron from each hydrogen atom. In this way the hydrogen atoms requirement is also fulfilled as they can also fill their capacity shells to their capacity of two electrons in their valence shells. By combining together they create the water molecule.
- - - - Atoms are the smallest unit of everything.
        
        Ex: Water is made up of water molecules, but water is made of atoms. There are two atoms of hydrogen and two atoms of oxygen in each water molecule. When atoms join together they from a molecule and when molecules join together they form a thing.
