Nomenclature Ionic & Covalent

Front

What is ionic nomenclature?

Back

Ionic nomenclature is the system used to name ionic compounds, which consist of cations (positively charged ions) and anions (negatively charged ions).

What is covalent nomenclature?

Back

Covalent nomenclature is the system used to name covalent compounds, which are formed by the sharing of electrons between nonmetals.

How do you determine the charge of a cation in ionic compounds?

Back

The charge of a cation is determined by the group number in the periodic table; for example, Group 1 elements form +1 cations, and Group 2 elements form +2 cations.

What is the significance of prefixes in covalent nomenclature?

Back

Prefixes indicate the number of atoms of each element in a covalent compound; for example, 'di-' means two, 'tri-' means three.

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.
