General chemistry

A model of the atom that explains emission and absorption of radiation as transitions between stationary electronic states in which the electron orbits the nucleus at a definite distance. The Bohr ...

Bohr radius

Chemistry; General chemistry

The atomic unit of length, equal to 0.529 177 2083 × 10-10 m, with an uncertainty of 0.000 000 0019 × 10-10 m (1998 CODATA values)

Resonance effect

Chemistry; General chemistry

If electron density at a particular point in a molecule is higher or lower than what you'd expect from a single Lewis structure, and various canonical structures can be drawn to show how electron ...

Aqua regia

Chemistry; General chemistry

A mixture of nitric and hydrochloric acids, usually 1:3 or 1:4 parts HNO3 to HCl, used to dissolve gold.

First ionisation energy

Chemistry; General chemistry

The energy needed to remove an electron from an isolated, neutral atom.

Oxidising agent

Chemistry; General chemistry

A reactant that removing electrons from other reactants in a chemical reaction. oxidising agents cause other substances to be oxidised in chemical reactions while they themselves are reduced. For ...

Valence bond theory

Chemistry; General chemistry

A theory that explains the shapes of molecules in terms of overlaps between half-filled atomic orbitals , or half filled "hybridized" orbitals (which are a mixture of atomic orbitals).
