Ions and 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 electric charge.

Front

What is the charge of a cation?

Back

A cation is a positively charged ion, formed when an atom loses electrons.

Front

What is the charge of an anion?

Back

An anion is a negatively charged ion, formed when an atom gains electrons.

Front

How do you determine the number of electrons in a positively charged ion?

Back

Subtract the charge number from the number of protons.

Front

What is the maximum number of electrons in the first orbit of a Bohr Model?

Back

The maximum number of electrons in the first orbit is 2.

Front

What is a valence electron?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

If an atom has 3 valence electrons, what charge will it have as an ion?

Back

The atom will have a charge of +3 as it loses 3 electrons.

Front

What happens to nitrogen's valence electrons when it forms an ionic bond?

Back

Nitrogen will gain 3 valence electrons.

Front

What is the formula for aluminium oxide?

Back

The correct formula for aluminium oxide is Al₂O₃.

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions, typically formed when electrons are transferred from one atom to another.
