单词	valence
释义	valenceva‧len‧ce /ˈveɪləns/ (also va‧len‧cy /-lənsi/) noun [countable] technical Word Origin WORD ORIGINvalence Origin: 1800-1900 Late Latin valentia ‘power, ability’, from valere; ➔ VALOR Examples EXAMPLES FROM THE CORPUS As with core levels, there are various approaches to the computation of valence level binding energies. Bonding may be ionic or covalent, depending on whether valence electrons are transferred or shared. In a pure semiconductor the valence band is essentially filled and the higher conduction band essentially empty. In molecules with unpaired valence electrons, spin-spin coupling between valence and core electrons leads to further small splittings. The patient will often refuse to go into a valence because he hates it. We know the way a patient gets into valences when he dramatizes his engrams in life. We see, then, that time, in the Orphic cosmological framework, has three valences. word sets WORD SETS► Chemistry acetate, nounacid, nounacidic, adjectiveacidify, verbactive, adjectiveadditive, nounagent, nounalchemy, nounalcohol, nounalkali, nounalkaline, adjectiveamalgam, nounantioxidant, noun-ate, suffixatomic number, nounbase, nounbauxite, nounbeaker, nounbenzene, nounbiochemistry, nounbitumen, nounbleach, nounbond, nounbonding, nouncalcify, verbcarbohydrate, nouncarbonate, nouncarbon dioxide, nouncarbonize, verbcatalyst, nouncaustic, adjectivechain reaction, nounchemical, nounchemical, adjectivechemical reaction, nounchemist, nounchemistry, nounchlorinate, verbcitric acid, nouncombustion, nounconcentration, nouncondense, verbcontaminant, nouncontaminate, verbcontaminated, adjectivecorrode, verbcorrosion, nouncorrosive, adjectivecrucible, nouncrystal, nouncrystallize, verbcyanide, nounDDT, noundecay, verbdecay, noundecompose, verbdegrade, verbderive, verbdetoxification, noundextrose, noundioxin, noundispersion, noundissolve, verbdistill, verbeffervesce, verbeffervescent, adjectiveelectrolysis, nounelectrolyte, nounelectroplate, verbemulsify, verbemulsion, nounenzyme, nounexpand, verbfatty acid, nounferment, verbferment, nounflashback, nounflask, nounformaldehyde, nounformula, nounfructose, nounfungicide, nounfuse, verbgas, noungaseous, adjectiveglucose, noungranular, adjectivegraphite, nounhallucinogen, nounhelium, nounherbicide, nounhydrate, nouninert, adjectiveinsoluble, adjectiveinsulin, nounion, nounionize, verblactic acid, nounlimescale, nounlitmus, nounlitmus paper, nounlitmus test, nounmethane, nounmixture, nounmolecule, nounneon, nounnerve gas, nounneutralize, verbneutron, nounnitric acid, nounnucleic acid, nounnucleus, nounnutrient, nounorganic chemistry, nounosmosis, nounoxidize, verboxyacetylene, nounoxygenate, verbozone, nounpart, nounpectin, nounpesticide, nounpestle, nounpetrochemical, nounpH, nounphotosynthesis, nounplasma, nounpolyunsaturated, adjectivepotash, nounprecipitate, verbprecipitate, nounprecipitation, nounproduct, nounprussic acid, nounquicklime, nounradioactive, adjectiveradioactivity, nounradiology, nounreact, verbreaction, nounreactive, adjectivereagent, nounresidue, nounretort, nounriboflavin, nounsalt, nounsaltpetre, nounsaturate, verbsaturated, adjectivesaturation, nounsaturation point, nounsemiconductor, nounsoft, adjectivesolid, nounsolution, nounsolvent, nounstability, nounstabilizer, nounstable, adjectivestarch, nounsteam, nounsucrose, nounsulphate, nounsulphide, nounsulphur, nounsulphur dioxide, nounsulphuric acid, nounsulphurous, adjectivesurface tension, nounsuspension, nounsynthesize, verbsynthetic, adjectivetannin, nountartaric acid, nounTNT, noununstable, adjectivevalence, nounvitamin, nounvolatile, adjectivevulcanize, verbwater softener, nounwater-soluble, adjectivewater vapour, nounwetting agent, noun 1a measure of the power of atoms to combine together to form compounds2another spelling of valance
