What are the three types of chemical bonding?

The transfer of electrons from a metal to a non-metal, forming oppositely charged ions.

A regular structure of ions held together by strong electrostatic forces between oppositely charged ions.

High melting and boiling points; conduct electricity when molten or dissolved in water.

What are the properties of ionic compounds?

The ions are free to move and carry charge.

Why do ionic compounds conduct electricity when molten or dissolved?

The sharing of pairs of electrons between two non-metal atoms.

Substances made of small molecules with strong covalent bonds but weak intermolecular forces.

Weak intermolecular forces require little energy to overcome.

Why do simple molecular substances have low melting and boiling points?

No, because they have no free electrons or charged particles to carry current.

Do simple molecular substances conduct electricity? Why or why not?

A structure where all atoms are bonded by strong covalent bonds in a large network.

Diamond and graphite (both forms of carbon).

Give two examples of giant covalent structures.

Each carbon atom forms four strong covalent bonds in a giant lattice.

Why does diamond have a high melting point?

It has delocalized electrons that can move through the layers.

The attraction between positive metal ions and a sea of delocalized electrons.

Delocalized electrons can move freely and transfer energy.

Why are metals good conductors of electricity and heat?

Layers of atoms can slide over each other without breaking the metallic bonds.

A mixture of metals or a metal with another element to improve its properties.

Different-sized atoms distort the layers, making it harder for them to slide over each other.

Long chains of repeating units (monomers) joined by covalent bonds.

Thermosoftening polymers melt when heated; thermosetting polymers do not because they have cross-links between chains.

What is the difference between thermosoftening and thermosetting polymers?

A single layer of carbon atoms arranged in a hexagonal lattice; it’s very strong and conducts electricity.

Molecules of carbon shaped like hollow spheres or tubes (e.g., Buckminsterfullerene).

Particles with a size between 1–100 nanometers (nm).

They have a high surface area to volume ratio, making them effective as catalysts, in medicine, and in electronics.

Why are nanoparticles useful in industry?

Potential harm to health and the environment due to their small size and reactivity.

What are the risks associated with nanoparticles?
