A
A substance composed of atoms joined together by covalent bond.
2
Q
Characteristics of covalent molecules:
A
- Force of attraction between molecules is weak.
- Have a relatively low melting point since little is needed to break the force of attraction between molecules.
- Tend not to conduct electricity since they don’t contain ions
3
Q
About Ionic compounds:
A
- formed by transfer of electrons from one atom to form stable ions.
- are made up of positive and negative ions.
- are neutral
4
Q
