Chapter 6 Practice

Atoms that gain or lose electrons are called

• metals.

• ions.

Ionization refers to the process of

• turning lithium into fluorine.

• losing or gaining electrons.

A compound differs from a mixture because it

• always remains frozen even at high temperatures.

• is held together by chemical bonds.

In which type of bond do atoms share electrons?

• covalent bonds

• ionic bonds

A carbon atom can bond to four other atoms because it has

• four valence electrons.

• no protons in its nucleus.

Atoms and ions are held together by

• stick bonds.

• chemical bonds.

Atoms sometimes form bonds to

• lose energy.

• become more stable by having a full outer energy level.

A covalent compound made of one sulfur and two oxygen atoms would be named

• sulfur dioxide

• sulfide oxygen

Covalent bonds are formed between

• ions.

• nonmetal atoms.

What is the correct Lewis Dot Structure for the oxygen atom (O)?

• 
•
