Compounds & Bonding

Flashcards reviewing key terms and concepts related to compounds, molecules, chemical formulas, valence electrons, and chemical bonding types.

Compound

A substance formed when two or more elements are combined, with properties that can be quite different than those of the elements within it.

Molecule

A structure made of more than one atom bonded together.

Chemical Formula

A representation using element symbols and numbers to show the proportion of each atom in a molecule (e.g., $CO_2$).

Valence Electrons

Electrons located in the outermost energy level of an atom that participate in bond formation to hold atoms together into molecules.

Ionic Bond

A strong chemical bond that holds atoms together tightly.

Covalent Bond

A type of chemical bond where shared electrons attract both atoms, holding them together tightly.

Hydrogen Bond

A bond characterized by a weak attraction between polar molecules.
