- adj. Univalent.
Century Dictionary and Cyclopedia
- Having the same valence or atomicity as hydrogen, represented by unity.
- adj. chemistry Of an element, consisting of a single atom in the molecule; for example: the noble gases. Note: strictly speaking, a molecule has at least two atoms.

“Ionization was also observed in monatomic inert gases, which proves that the unit of electric charge is a constituent of the atom that is liberated from it by ionization.”
“Due to their antisocial and imperturbable nature they occur in ChemicalData as only their monatomic selves.”
“These atoms still try to reshape even after forming a molecule but find their efforts opposed by the new covalent bond, the covalent bond gets broken by this reshaping force when the molecule moves to a spatial position where the Casimir force changes sufficiently that the reshaping force disassociates the molecule restoring monatomic energy levels.”
“Einstein has made great contributions to the scientific world, including the theory of relativity, the founding of relativistic cosmology, the prediction of the deflection of light by gravity, the quantum theory of atomic motion in solids, the zero-point energy concept, and the quantum theory of a monatomic gas which predicted Bose–Einstein condensation, to name a few of his scientific contributions.”
“This releases the signature black light plasma and restores the atoms to monatomic levels.”
“The gas has been allowed to equilibrate at some well defined temperature, and as a result the average kinetic energy of each molecule is (3/2) kT (we ignore internal degrees of freedom and assume the gas is monatomic), where”
“Water can be cheaply disassociated into Brown's Gas/HHO gas (monatomic and diatomic Hydrogen and Oxygen) using efficient electrolyzing techniques which require very little power to operate, or sophistication to build.”
“The terms "Brown Gas" and "HHO" are used in this article as synonymous, although there is some minor technical debate as to the ratios of monatomic and diatomic gas within each, and "HHO" was once a trade name for Brown's Gas (it has now become a generic term like "kleenex", as iswritten here for this purpose).”
“Not to be confused with the Biblical manna … the monatomic white gold that made the Ark of the Covenant fly …”
“For a monatomic ideal gas the temperature is related to the translational motion or average speed of the atoms.”
