Give 2 differences between an ionic compound and a covalent compound.

1. Ionic compounds are formed by the transfer of electrons that are positively and negatively charged, whereas, covalent compounds are formed by sharing the electrons.

2. In an ionic compound, bonding involves a metal and nonmetal, whereas, in the covalent compound, bonding is between nonmetals.

3.Ionic compounds are more soluble in water than covalent compounds.

4. Ionic compounds have definite shape whereas, covalent has no shape.

5. Ionic compounds are the good conductor of electricity, whereas covalent compounds are the bad conductor of electricity.

Sorry I gave more than two, just choose two of them that you like! :)

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
