Molecular Compounds

Atoms held together by sharing electrons are:

• covalently bonded

• ionically bonded

• metallically bonded

• Metallica

What is the difference between an atom and a molecule?

• Atoms are singly bonded and molecules are particles made of two bonds

• Atoms are single particles and molecules are particles made of two or more atoms bonded together

• Molecules are single particles and atoms are particles made of two or more atoms bonded together

• The way they are chemically bonded

What is a molecular formula

• an atomic mass

• a molecular weight

• The chemical formula of a ionic compound

• The chemical formula of a molecular compound

What type of compounds have high boiling points?

• metallic

• ionic

• covalent

• organometallic

Why can't molecular compounds conduct electricity?

• The electrons are not able to freely flow very well

• They do conduct electricity. Trick question.

• The bonds are not able to freely rotate.

• The lattice structure prevents it.
