Defenitions Of Stuff

A d-block element which forms at least one stable ion with a partially filled d-sub shell

Atom with the same number of protons but different number of neutrons

Weighted mean mass of an atom of an element compared to 1/12 of the mass of an atom of carbon-12

Mass of an atom of an isotope of an element compared to 1/12 of the mass of an atom of carbon-12

Average mass of a molecule compared to 1/12 of the mass of an atom of carbon-12

Average mass of a formula unit compared to 1/12 of the mass of an atom of carbon-12

Proton donor

Proton acceptor

Loss of electrons

Gain in electrons

Accepts electrons and gets reduced

Donates electrons and gets oxidised

Electrostatic attraction between two oppositely charged ions

Strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms

One atom provides both of the electrons

Energy needed to remove one mole of electrons from one mole of gaseous atoms

If there is a change in concentration,pressure or temperature-equilibrium will move to help counteract change

Measure of dispersal of energy in a system

Entropy content of one mole of a substance under standard conditions

Total enthalpy change of a reaction is always the same, no matter which route is taken

Catalyst which is in different phase to reactants

Catalyst which is in the same state as reactants
