Chemistry Quiz

The structure of elements or compounds determines the properties of them.

• True

• False

Extended structures are when all atoms are connected together.

• True

• False

Nonpolar compounds like oil dissolve in polar compounds like water.

• True

• False

Element is a substance made of only one type of atom.

• True

• False

Molecules are a group of atoms that are held together by chemical bonds and act as a unit. The units are not connected.

• True

• False

Compounds can exist in just the molecular structure.

• True

• False

If a compound has extended structure, it will be a good conductor of electricity.

• True

• False

Which type of compounds usually have high melting and boiling points?

• Ionic compounds

• Covalent compounds

• Polar covalent compounds

• Nonpolar covalent compounds

What are the properties of covalent compounds?

• High melting and boiling points, good conductors of electricity

• Low melting and boiling points, poor conductors of electricity

• High attraction between atoms, extended structures form

• Low attraction between atoms, individual atoms form

Which type of compound will NOT easily dissolve in a polar compound like water?

• Ionic compound

• Covalent compound

• Nonpolar covalent compound

• Polar covalent compound
