Effect of Atomic Structure

1. Which substances are capable of conducting electricity?

1.1. Ionic

1.1.1. Can conduct electricity when:

1.1.2. It has melted to form a liquid

1.1.3. It has dissolved in water to form aqueous solution

1.2. Metallic

1.2.1. Can conduct electricity when:

1.2.2. In solid state

1.2.3. In molten state

1.2.4. *good conductor because electrons in the electron sea are free to flow and carry electric current.

1.3. Molecular

1.3.1. Can’t conduct electricity.

1.4. Covalent

1.4.1. Can’t conduct electricity.

2. All forces found in the following substances (ranked from strongest to weakest):

2.1. Ionic

2.1.1. 1. Ionic bond

2.1.2. 2. London Dispersion

2.2. Covalent

2.2.1. 1. Covalent bond

2.2.2. Dispersion

2.3. Metallic

2.3.1. 1. Metallic bond

2.3.2. 2. Dispersion

2.4. Molecular

2.4.1. 1. Hydrogen bonding

2.4.2. 2. Dipole- dipole

2.4.3. 3. London dispersion

3. Expected melting points (ranked from highest to lowest):

3.1. 1. Covalent

3.1.1. Much higher melting point compared to ionic and molecular.

3.2. 2. Ionic

3.2.1. High melting point.

3.3. 3. Molecular

3.3.1. Low to moderate melting point

3.4. ? Metallic

3.4.1. Low to very high melting point, therefore it varies and can't be ranked.
