Ionic vs. Covalent Compounds

These flashcards cover key concepts related to ionic and covalent compounds, their properties, and ions.

Ionic Compounds

Compounds where electrons are transferred from one atom to another.

Covalent Compounds

Compounds where electrons are shared between atoms.

Melting Point of Ionic Compounds

High melting point.

Melting Point of Covalent Compounds

Low melting point.

Electrical Conductivity of Ionic Compounds

Can conduct electricity when melted or dissolved in water.

Electrical Conductivity of Covalent Compounds

Generally do not conduct electricity, except for acids.

Composition of Ionic Compounds

Made up of metal and nonmetal elements.

Composition of Covalent Compounds

Made up of nonmetal elements.

Ionic Compound Components

Referred to as formula units.

Covalent Compound Components

Referred to as molecules.

Ion

An atom that has gained or lost electrons and has a charge.

Cation

A positively charged ion, formed by losing electrons.

Anion

A negatively charged ion, formed by gaining electrons.

Full Octet

Having eight valence electrons, characteristic of noble gases.

Valence Electrons

Electrons in the outermost shell of an atom that are involved in bonding.

Sodium Ion (Na+)

Formed when sodium loses one electron.

Chloride Ion (Cl-)

Formed when chlorine gains one electron.
