Concept 3: Naming Covalent Compounds

Describe the difference between single, double, and triple bonds.

A single bond is 2 electrons shared. A double bond is 4 electrons shared. A triple bond is 6 electrons shared.

Classify the following as an atom, ionic compound, or molecule: Ne

Molecule

Covalent bond

A bond that results between nonmetallic elements that share electrons.

Molecule

A compound that's formed when 2 or more elements are covalently bonded.

Explain why a covalent bond forms, how it forms, and what types of elements form them.

A covalent bond forms to become stable. It forms by sharing electrons between nonmetallic elements.

Classify the following as an atom, ionic compound, or molecule: KCl

Ionic compound

Classify the following as an atom, ionic compound, or molecule: NH₄Cl

Ionic compound

Differentiate between the properties of covalent compounds and ionic compounds.

Ionic compounds are formed by the transfer of electrons, while covalent compounds are formed by the sharing of electrons.

Determine the chemical formula for the following covalent compounds: Sulfur dioxide

SO₂
