A
In pairs of atoms
4
Q
What happens as you go down g7?
A
- The elements get less reactive as it is harder to gain an electron when the outer shell is further from nucleus
- Higher melting and boiling points
- Higher relative atomic masses
5

A
- Covalent bonding with other non-metals (form simple molecular structures)
- Ionic bonding with metals
6
