Ionic Compound
A stable form of an ionic compound that forms a crystal lattice rather than a molecule.
2
New cards
Crystal Lattice
A rigid three-dimensional arrangement of ions in an ionic compound.
3
New cards
Formula Weight
The sum of the atomic weights of the atoms shown in the formula of an ionic compound.
4
New cards
Avogadro's Number
6.022 x 10^23, representing the number of entities in one mole of a substance.
5
New cards
Covalent Bonding
A type of bonding where atoms share valence electrons to satisfy the octet rule.
6
New cards
Lewis Structure
A diagram that represents the bonding between atoms and the lone pairs of electrons in a molecule.
7
New cards
Sharing Electrons
Occurs when electron-containing orbitals of atoms overlap, forming a covalent bond.
8
New cards
Octet Rule
The principle that atoms tend to bond in such a way that they each have eight electrons in their valence shell.
9
New cards
Double Bond
A type of covalent bond where two pairs of electrons are shared between two atoms.
10
New cards
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.
