A
An atom joined together in covalent
2
Q
What do molecules have?
A
- Low Boiling and Melting points
- Atoms held together by covalent bonds
- No overall electric charge which doesn’t conduct electricity

Q
How does a solid turn into a gas?
A
Solid melts and gives energy which is breaking the force of attraction and is then turned into a liquid, the liquid is then evaporated into a gas
