1. Reactivity decreases in the first group downwards ..
2. Reactivity increases upwards in non-metals...
3. Melting and boiling point decreases downwards in Metals.
4. Elements are arranged according to their proton number.
5. Most elements have more neutrons than protons.
6. In a lattice electrostatic forces are the reason why it is so strong.
7. Covalent Compounds are easier to break than Ionic Compounds.
8. All Elements in Group VII and VIII are Diatomic.
9. Group 0 Elements are unreactive
10. Ethanol is a volatile liquid
11. Organic Compounds are insoluble in water.
12. Oil and Ethanol will mix with each other.
13. Diatomic Molecules all form Covalent bonds.
