Front

An ionic bond is the attraction between oppositely charged ions.

Back

An ionic bond forms when electrons are transferred from one atom to another, resulting in the formation of ions.

Front

Boron is in the same group as aluminum and has 3 valence electrons.

Back

Boron, like aluminum, is a group 13 element and shares similar chemical properties.

Front

In the chemical formula MgBr₂, the "2" indicates there are two bromide ions for every magnesium ion.

Back

This indicates the ratio of ions in the compound, essential for understanding its composition.
