1. Atoms

1.1. Made up of

1.1.1. Proton (+)

1.1.2. Neutron (0)

1.1.3. Electron (-)

1.2. Ways to rep elements

1.2.1. Diagram

1.2.2. Nucleon Number

2. Isotopes

2.1. Formula in finding Relative Atomic Mass

2.1.1. {[(A1/100) x B1] +[(A2/100) x B2]}

2.2. Same element with same number of protons and electrons.

2.2.1. THUS

2.2.1.1. similar chemical properties

2.3. Different number of neutrons

2.3.1. THUS

2.3.1.1. different physical properties

3. Radioisotopes

3.1. Emits high-energy radiation

3.2. Caused damage to cells and causes cancer

3.3. DANGEROUS!

3.4. Important applications if handled properly

3.5. Unstable nuclei thus dissipate their energy by continuously emitting radiation.

4. Arrangement of atoms
