- Atoms
- Nucleus
- its in the middle in the Atom
- It contains both Protons and Neutrons
- The nucleus has an overall positive charge
- Protons are positively charged and the Neutrons have no charge
- Electrons
- They move around the nucleus
- They have a negative charge
- They occupy shells around the nucleus
- The first shell takes 2 electrons and and shell after takes 8
- They have virtually no Mass
- Extra Information
- Neutral atoms have no charge overall
- The charge on the electron is the same size as the charge on the proton just opposite
- the number of protons always equals the number of electrons in a neutral atom
- If electrons are added or removed then the atom becomes charged
- It is then called an ION
