Atomic orbitals |
A region around the nucleus that can hold up to 2 electrons with opposite spins |
|
|
Principal quantum number, n |
A number representing the overall energy of each orbital, which increases with distance from the nucleus. The sets of orbitals with the same n-value are referred to as electron shells or energy levels. |
|
|
Ionic bonding |
The electrostatic attraction between cations and anions |
|
|
Giant ionic lattice |
A 3D structure of oppositely charged ions, bonded together by strong ionic bonds |
|
|
Covalent bonding |
The strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms |
|
|
Giant covalent lattice |
3D structure of atoms, bonded together by strong covalent bonds |
|
|
Molecule |
The smallest part of a covalent compound that can exist while retaining its chemical identity, consisting of 2 or more atoms covalently bonded together |

|
|
Dative covalent bond |
A shared pair of electrons in which the bonded pair has been provided by one of the bonding atoms only |
|
|
Average bond enthalpy |
The average enthalpy change that takes place when breaking by breaking homolytic fission 1 mol of a given type of bond in the molecules of a gaseous species |
