What is it called if there are three pairs of electrons are being shared?

• If three pairs of electrons are being shared it is called a triple bond.
• If three pairs of electrons are being shared it is called a double bond.
• If three pairs of electrons are being shared it is called a single bond.
• all of the above

Rank the three types of bonds in order of increasing strength.

• single bonds, double bonds, triple bonds
• triple bonds, double bonds, single bonds
• double bonds, triple bonds, single bonds
• single bonds, triple bonds, double bonds

What do the prefixes in front of the element name tell us?

• They tell us how many atoms of that element are present in the molecule.
• They tell us how many elements are present in the molecule.
• They tell us how many molecules are present.
• none of the above

What do atoms that form positive ions tend to do?

• The positive ion will be formed from an atom that has a tendency to lose electrons.
• The positive ion will be formed from an atom that has a tendency to gain electrons.
• The positive ion will be formed from an atom that has a tendency to keep the same amount of electrons.
• The positive ion will be formed from an atom that has a tendency to share electrons.
