Lecture Notes on Chemical Bonds

This set of flashcards covers key concepts related to chemical bonding, including definitions of compounds, ions, and types of bonds.

Combined Elements

Combining elements creates new properties that are distinct from the individual elements.

Compound

A substance formed when two or more elements are chemically combined in a fixed proportion.

Chemical Formula

A notation that shows the elements in a compound and the exact number of atoms of each element.

Octet Rule

Atoms are most stable when they have 8 electrons in their outer energy level.

Cation

An atom with an overall positive charge due to losing electrons.

Anion

An atom with an overall negative charge due to gaining electrons.

Ionic Bond

The force of attraction between the opposite charges of ions in an ionic compound.

Oxidation Number

The charge on an atom that can indicate its stability and bonding behavior.

Lewis Structure

A diagram that represents the bonding between atoms and the lone pairs of electrons in a molecule.

Covalent Bond

A bond formed by the sharing of a pair of electrons between atoms.
