Ionic Bonding

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions, typically formed when one atom donates electrons to another, resulting in the formation of cations and anions.

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 cation?

Back

A cation has a positive charge, formed when an atom loses one or more electrons.

Front

What is the charge of an anion?

Back

An anion has a negative charge, formed when an atom gains one or more electrons.

Front

How do you determine the formula for ionic compounds?

Back

The formula for ionic compounds is determined by balancing the total positive and negative charges of the ions involved.

What is the formula for aluminum sulfite?

Back

The formula for aluminum sulfite is Al₂(SO₃)₃.

Front

What ion does nitrogen typically form?

Back

Nitrogen typically forms a nitride ion with a charge of -3 (N³-).

Front

What does a 3- charge on an anion indicate about electron gain?

Back

A 3- charge indicates that the anion has gained 3 electrons.
