Ionic Bonding Review

Ionic bonds form between...

• a metal & nonmetal

• metals only

• nonmetals only

Two ions each with a negative charge will...

• attract one another and form a bond

• repel each other and will not bond

Two ions each with a positive charge will...

• attract one another and form a bond

• repel each other and will not bond

How are ions formed?

• the loss of one or more electrons

• the gain of one or more electrons

• Either the loss or gain of one or more electrons

A positive ion (also called a cation) forms because of?

• The loss of one or more electrons

• The gain of one or more electrons

A negative ion (also called a anion) forms because of?

• The loss of one or more electrons

• The gain of one or more electrons

Metals (elements on the left side of the PT) tend to

• lose electrons and form a positively charged ion

• gain electrons and form a negatively charged ion

Nonmetals (elements on the right side of the PT) tend to

• lose electrons and become positively charged ions

• gain electrons and become negatively charged ions

Ionic bonds form due to...

• like charges attracting

• opposite charges attracting

How many Lithium ions are needed to balance out the negative 2 charge on oxygen? Lithium (Li⁺) and oxygen (O^2-)

• 1 Lithium ion is needed to balance the oxygen ion

• 2 Lithium ions are needed to balance the oxygen ion
