What's the difference between monatomic and polyatomic?

Monatomic


Definition:

  • (adv.) Consisting of, or containing, one atom; as, the molecule of mercury is monatomic.
  • (adv.) Having the equivalence or replacing power of an atom of hydrogen; univalent; as, the methyl radical is monatomic.

Example Sentences:

  • (1) As a particular result phase shifts of pi and 0.9 pi were measured for monatomic steps on (111)gold and (111)platinum surfaces, respectively.
  • (2) It is concluded that there will be a significant improvement in the detection of monolayers on a homogeneous monatomic substrate by using coincidence of energy-loss electrons with Auger electrons.
  • (3) Monatomic ions such as Na(+), Li(+), Cl(-), Ca(2+) therefore have a larger extracellular space available than is calculated on the basis of the inulin space.5.
  • (4) The method extends the previous work on image computations of monatomic species objects using small point-like model representations of atom positions.
  • (5) The background ions of both polarities are similar to those found in keV particle bombardment by monatomic projectiles.

Polyatomic


Definition:

  • (a.) Having more than one atom in the molecule; consisting of several atoms.
  • (a.) Having a valence greater than one.

Example Sentences:

  • (1) The possibilities are shown of using officinal glycerin as a polyatomic alcohol in the treatment of alcoholism, in particular, alcohol abstinent syndrome.
  • (2) The results for iron, cobalt, copper, and zinc were corrected for interferences from polyatomic ions by using a blank solution containing the same concentration of sodium, sulfur, chlorine, and calcium as human serum.
  • (3) The relative binding affinities of various monovalent alkali metal and polyatomic cations for the TTX-receptor site showed that this site displayed cation discrimination properties which were similar to those reported previously for the electrically excitable sodium channel in intact nerve fibers.
  • (4) For polyatomic anions the predictions agree approximately but not completely with observations.
  • (5) By using high mass resolution we succeeded in detecting and localizing 99Tc in cell sections by eliminating polyatomic ions that arise from this biological matrix.
  • (6) The interface atomizes the macromolecule in a microwave discharge and produces simple polyatomic molecules from the elements contained in the analyte by reaction with a scavenger gas.
  • (7) The topography of the cells is given by the image of the polyatomic ion 26CN-.
  • (8) These included monoatomic anions Cl- and Br-, which bind to the so-called halorhodopsin binding sites I and II, and polyatomic anions NO3- and ClO4-, which bind to site I only.
  • (9) The differences in position of the polyatomic anions in the two sequences indicates that the "binding" site is accessible but that transport is limited by steric factors.
  • (10) The permeability sequence for large polyatomic anions was formate greater than bicarbonate greater than acetate greater than phosphate greater than propionate for GABAR channels; phosphate and propionate were not measurably permeant in GlyR channels.
  • (11) Relative proportions of monoatomic and polyatomic emission vary in epoxy, gelatin and tissue.
  • (12) At present the most important limitation of this method is mass overlap by polyatomic species for some elements of interest (e.g., Cr, Mn, and V).
  • (13) However, we find that two Schiff base frequencies characterize halorhodopsin upon binding of the polyatomic anions.
  • (14) Thus, large polyatomic ions can cause secondary-ion desorption even at very low velocity.
  • (15) The additional ionization yield through the nonmetastable Penning processes reaches a maximum abruptly at very low partial pressure of polyatomic admixtures (alkanes), decreasing steadily with higher admixture partial pressure.
