Atomic Structure and Radiation

Atomic Structure and Radiation

1. Proton-Positively charged atoms with mass of 1

2. Neutron-Neutral atoms with mass of 1

3. Electron-Negatively charged atoms with mass of almost 0

4. Alpha (Low Penetration and High Ionising) ,Beta and Gamma (High Penetration and Low Ionising) radiation are the types of radiation.

5. Half Life=The amount of time it takes for the radiation of something to decrease by half

6. Ions can be irradiated or contaminated

7. The model of the atom has changed over time with Plum Pudding, Nuclear and Modern versions of the atom

8. Connects with Chemistry Paper 1- Atomic Structure and Periodic Table
