Front

What happens to Beryllium when it forms an ionic bond?

Back

Beryllium will lose 2 valence electrons when forming an ionic bond.

Front

What is an ionic bond?

Back

An ionic bond is the electrostatic attraction between oppositely charged ions.

Front

What type of bonding is characterized by the sharing of electrons?

Back

Covalent bonding is characterized by the sharing of electrons.

Front

What is the charge of a Calcium ion when it forms an ionic bond?

Back

Calcium typically loses 2 electrons to form a Ca²⁺ ion.

Front

What is the charge of a Phosphorus ion when it gains electrons?

Back

Phosphorus typically gains 3 electrons to form a P³⁻ ion.

Front

What is the ionic formula for a bond between Calcium and Phosphorus?

Back

The ionic formula is Ca₃P₂.

Front

What is the result of the attraction between two oppositely charged ions?

Back

The result is the formation of an ionic bond.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.
