Front

What is a crystal lattice?

Back

A three-dimensional arrangement of atoms or molecules in a crystalline solid.

Front

What distinguishes ionic solids from covalent solids?

Back

Ionic solids are formed by ionic bonds between charged ions, while covalent solids are formed by covalent bonds between atoms.

Front

What is the melting point of crystalline solids?

Back

Crystalline solids have a defined melting point.

Front

What is the electrical conductivity of metallic solids?

Back

Metallic solids can conduct electricity due to the presence of free-moving electrons.

Front

What is the difference between molecular solids and ionic solids?

Back

Molecular solids are held together by intermolecular forces, while ionic solids are held together by ionic bonds.
