- Bonding and calculations.
- Atoms, compounds and isotopes.
- Atoms.
- These are very small, they contain 3 even smaller particles
- Electrons
- They have the same amount as protons
- They have a mass of 1/2000 or very small
- They have a charge of -1
- They are found in the outer shells of the atom
- Protons
- You can find the amount of these in a atom by looking at the bottom number on the periodic table
- There charge is +1
- They have a relative mass of 1
- They are found in the center of and atom in the nuleus
- Neutrons
- you work out the number of these by taking the atomic proton number (bottom) of the atomic mass (top)
- They have a charge of 0
- They are located in the center of the atom
- They have a mass of 1
- Electrons
- These are very small, they contain 3 even smaller particles
- Compounds
- These are chemically combined
- These are made when atoms of two or more elemants are chemically combined
- For example, Carbon Dioxide is a compound.
- Isotopes
- Atoms.
