Magic Numbers
Particular numbers of protons or neutrons that give a nucleus exceptional stability.
Inorganic & Coordination ChemistryMagnetic Moment of Complexes
The magnetic behaviour of a complex, determined by the number of unpaired electrons it contains.
Atomic Structure & PeriodicityMagnetic Quantum Number
The quantum number mₗ that specifies the spatial orientation of an orbital relative to an applied magnetic field.
Chemical EquilibriumMagnitude of K and Extent of Reaction
The use of the size of the equilibrium constant to judge how far a reaction proceeds before equilibrium is reached.
Organic ChemistryMarkovnikov's Rule
In the addition of a protic acid to an unsymmetrical alkene, the hydrogen attaches to the carbon already bearing more hydrogens.
Nuclear & RadiochemistryMass Defect
The difference between the mass of a nucleus and the sum of the masses of its constituent nucleons.
Atomic Structure & PeriodicityMass Number
The total number of protons and neutrons in an atomic nucleus.
Solutions & Colligative PropertiesMass Percentage
The mass of solute expressed as a percentage of the total mass of the solution.
Analytical Chemistry & SpectroscopyMass Spectrometry
A technique that separates ionised molecules and fragments according to their mass-to-charge ratio.
Analytical Chemistry & SpectroscopyMatrix
Everything in a sample other than the analyte itself.
Foundations of ChemistryMatter
Anything that occupies space and possesses rest mass, existing in the solid, liquid, gas or plasma state.
Thermochemistry & ThermodynamicsMaximum Work
The greatest amount of work obtainable from a change of state, achieved only along a reversible path.
States of Matter & Gas LawsMaxwell–Boltzmann Distribution
The statistical distribution describing how molecular speeds are spread within a gas at a given temperature.
States of Matter & Gas LawsMelting Point
The temperature at which the solid and liquid phases of a substance coexist in equilibrium at a given pressure.
Biochemistry & Polymer ChemistryMetabolism
The complete set of chemical reactions occurring within a living organism.
Inorganic & Coordination ChemistryMetal Carbonyl
A coordination compound in which carbon monoxide molecules are bonded to a metal centre.
Chemical Bonding & Molecular StructureMetallic Bond
The attraction between a lattice of metal cations and the delocalised electrons that move freely throughout the structure.
Atomic Structure & PeriodicityMetallic Character
The tendency of an element to lose electrons and display typical metallic properties such as lustre, malleability and conductivity.
Atomic Structure & PeriodicityMetalloid
An element with properties intermediate between those of metals and non-metals, lying along the periodic table's staircase.
Inorganic & Coordination ChemistryMetallurgy
The science and technology of extracting metals from their ores and preparing them for use.
Acids, Bases & SaltsMethyl Orange
An acid–base indicator that is red in acid and yellow in alkali, changing between pH 3.1 and 4.4.
Solutions & Colligative PropertiesMicelle
A spherical aggregate of surfactant molecules that forms in solution above a characteristic concentration.
Chemical Kinetics & CatalysisMichaelis–Menten Kinetics
The standard model of enzyme kinetics, in which rate rises with substrate concentration until the enzyme becomes saturated.
Inorganic & Coordination ChemistryMineral
A naturally occurring inorganic solid with a definite chemical composition and an ordered crystal structure.
