Types of Solids in Chemistry

What are the three main types of solids in chemistry?

• Crystalline solids, amorphous solids, and polymers

• Transparent solids, opaque solids, and translucent solids

• Metallic solids, ionic solids, and covalent solids

• Liquid solids, gas solids, and plasma solids

How do ionic solids form?

• Formation through van der Waals forces

• Attraction between positively and negatively charged ions

• Formation through metallic bonding

• Formation through covalent bonding

What is the defining characteristic of metallic solids?

• Highly reactive with water

• Absence of delocalized electrons

• Presence of delocalized electrons

• Presence of localized electrons

Give an example of a covalent network solid.

• Silicon dioxide

• Graphite

• Diamond

• Sodium chloride

What type of bonding is present in molecular solids?

• Ionic bonds

• Covalent bonds

• Metallic bonds

• Intermolecular forces

Explain the structure of an ionic solid.

• Ionic solids have a three-dimensional lattice structure with alternating positive and negative ions held together by strong electrostatic forces.

• Ionic solids have a two-dimensional lattice structure.

• Ionic solids are composed of covalent bonds between ions.

• Ionic solids have a linear structure with no lattice arrangement.

What are the properties of metallic solids?

• Low electrical conductivity and high opacity

• Low thermal conductivity and ductility

• Brittle and transparent

• High electrical and thermal conductivity, malleability, ductility, luster, and opacity

How do molecular solids differ from other types of solids?

• Molecular solids have a crystalline structure unlike other types of solids.

• Molecular solids have stronger intermolecular forces compared to other types of solids.

• Molecular solids are always metallic in nature.

• Molecular solids have weaker intermolecular forces compared to other types of solids.

What is the role of intermolecular forces in molecular solids?

• Intermolecular forces only exist in ionic solids, not molecular solids.

• Intermolecular forces hold the molecules together in molecular solids.

• Intermolecular forces have no effect on the structure of molecular solids.

• Intermolecular forces repel the molecules in molecular solids.

Discuss the properties of covalent network solids.

• Covalent network solids exhibit high electrical conductivity in the solid state.

• Covalent network solids have low melting and boiling points.

• Covalent network solids are malleable.

• Covalent network solids have high melting and boiling points, hardness, lack of electrical conductivity in the solid state, and brittleness.
