Question

A substance conducts an electric current when it is in the liquid state. What would the conductivity of the substance in solid form indicate about the type of bond in the substance? If the solid is conductive, the bonds are ionic. If the solid is not conductive, the bonds are covalent. If the solid is conductive, the bonds are metallic. If the solid is not conductive, the bonds are metallic.

Answer 1

We have three types of bonds :

1.) Bonds between metals - Metallic bonds.

2.) Bonds between non metals - Covalent bonds

3.) Bonds between metals and non metals - Ionic bonds

Metallic bonds form structures which conduct electricity in both liquid and solid state.

This is because they have electrons that are mobile within their structures.

Ionic bonds form structures which conduct electricity only in liquid state that is in solution form.

This is because in solution form the ions are mobile and thus electricity can flow but in solid state the ions are fixed.

Covalent bonds form structures which are poor conductors whether in liquid or in solid state since they neither have free ions or even electrons.

The answer is thus :

IF THE SOLID IS CONDUCTIVE THEN THE BONDS ARE METALLIC.

Answer 2

We have three types of bonds :

1.) Bonds between metals - Metallic bonds.

2.) Bonds between non metals - Covalent bonds

3.) Bonds between metals and non metals - Ionic bonds

Metallic bonds form structures which conduct electricity in both liquid and solid state.

This is because they have electrons that are mobile within their structures.

Ionic bonds form structures which conduct electricity only in liquid state that is in solution form.
