CHM103_Chapter_4.2

Ionic Compound

A stable form of an ionic compound that forms a crystal lattice rather than a molecule.

Crystal Lattice

A rigid three-dimensional arrangement of ions in an ionic compound.

Formula Weight

The sum of the atomic weights of the atoms shown in the formula of an ionic compound.

Avogadro's Number

6.022 x 10^23, representing the number of entities in one mole of a substance.

Covalent Bonding

A type of bonding where atoms share valence electrons to satisfy the octet rule.

Lewis Structure

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

Sharing Electrons

Occurs when electron-containing orbitals of atoms overlap, forming a covalent bond.

Octet Rule

The principle that atoms tend to bond in such a way that they each have eight electrons in their valence shell.

Double Bond

A type of covalent bond where two pairs of electrons are shared between two atoms.

Super-Octet Structure

A structure in which elements can have more than eight electrons in their valence shell, often found in elements of the third period or higher.
