Ionic Bonding

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge.

Front

What is the charge of a positive ion?

Back

A positive ion, or cation, has more protons than electrons, resulting in a net positive charge.

Front

What is the charge of a negative ion?

Back

A negative ion, or anion, has more electrons than protons, resulting in a net negative charge.

Front

What do ions seek to achieve when they form?

Back

Ions seek to achieve a stable electron configuration, often resembling that of noble gases.

Front

Which group of elements tends to form positive ions?

Back

Metals tend to form positive ions.

Front

Which group of elements tends to form negative ions?

Back

Nonmetals tend to form negative ions.

Front

What is the electron configuration of a noble gas?

Back

The electron configuration of a noble gas is complete, meaning it has a full outer shell of electrons.

Front

What is the charge of a nitrogen ion?

Back

A nitrogen ion typically has a charge of 3-.

Front

What is the formula for sodium phosphide?

Back

The formula for sodium phosphide is Na₃P.

Front

How do you determine the formula of an ionic compound?

Back

The formula of an ionic compound is determined by balancing the charges of the cations and anions.
