Qhov ruaj khov heev zoo gasses , suav nrog helium, neon, argon, krypton, xenon thiab radon, yog tag nrho cov ntsiab lus uas tsis yog hlau. Cov ntsiab lus no tsim kev sib raug zoo nrog ib leeg los ntawm kev sib koom electrons los ua cov sib txuas.
Ib yam li ntawd, tej zaum koj yuav nug, hom ntawv cog lus twg yog neon?
A neon atom (Ne) collides nrog ib tug oxygen atom ntawm ib tug molecule (O2) nrog nws daim ntawv cog lus kev taw qhia (Daim duab E2. 8). Lub zog kinetic ntawm Ne atom yog K1= 6 × 10–21 J. Oxygen daim ntawv cog lus rigidity coefficient β yog 1.18 × 103 N/m.
Ib yam li ntawd, puas yog Neon sib xyaw lossis sib xyaw? Neon yog ib lub caij vim nws tsuas muaj atoms ntawm Neon ; tag nrho cov atoms nyob rau hauv ib qho piv txwv ntawm Neon muaj 10 protons. Thaum Neon tsis tshua muaj tshwm sim nrog lwm yam tshuaj, yog tias nws yuav ua li ntawd, ces nws yuav tsim ib qho compound vim qhov no muaj cov atom ntawm ib lub caij sib txawv.
Yog li ntawd, yog neon ionic lossis molecular?
Neon yog chemically inert, thiab tsis muaj uncharged neon cov tebchaw paub. Cov compounds ntawm neon paub tam sim no suav nrog ionic molecules , molecules tuav ua ke los ntawm van der Waals rog thiab clathrates.
Cov ntsiab lus twg muaj feem yuav muaj ionic covalent bonds?
Ionic daim ntawv cog lus feem ntau tshwm sim ntawm hlau thiab nonmetal ions . Piv txwv li, sodium (Na), hlau, thiab chloride (Cl), nonmetal, tsim ib qho ionic daim ntawv cog lus ua NaCl. Hauv ib covalent bond , cov atom daim ntawv cog lus los ntawm kev sib koom electrons. Covalent bonds feem ntau tshwm sim ntawm nonmetals.
Pom zoo:
Puas yog o3 covalent lossis ionic?
Lub O3 molecule muaj peb cov pa oxygen atoms, ib qho kev sib koom ua ke covalent daim ntawv cog lus thiab ib daim ntawv cog lus ob npaug. Ob lub O-O uas sib koom ua ke ob qho kev sib cog lus yog nonpolar vim tias tsis muaj electronegativity ntawm cov atoms ntawm tib lub caij, sib koom tib cov xov tooj ntawm electrons
Puas yog aluminium nitrite ionic lossis covalent?
Aluminium nitrite muaj cov aluminium cation Al3+ thiab polyatomic nitrite anion NO − 2. Txij li thaum lub ionic compound yuav tsum nyob nruab nrab, tus naj npawb ntawm txhua ion yuav tsum ua rau tag nrho cov nqi ntawm xoom
Puas yog potassium phosphide ionic lossis covalent?
Txhawm rau sib npaug qhov no (kom tus nqi ntawm cov ntsev nruab nrab peb xav tau 3 poov tshuaj rau txhua 1 phosphideanion. Qhov no muab ib chav tsev ntawm (K +) 3 (P-), uas tau qhia hauv Lewis qauv. Tsis tas li ntawd, vim qhov no yog ib qho ionic compound, tsis muaj kev sib txuas ncaj qha tshwm sim
Puas yog aluminium bromide ionic lossis covalent?
Lesson Summary Aluminium bromide yog ib qho ionic compound uas yog tsim los ntawm cov tshuaj tiv thaiv ntawm txhuas nrog kua bromine. Aluminium atoms muab peb lub electrons ua rau Al + 3 thiab bromine atoms nce ib lub electron txhua qhov ua rau Br-1
Koj tuaj yeem sim ua li cas thiaj txiav txim siab seb qhov sib xyaw puas yog ionic lossis covalent?
Muaj ob peb txoj hauv kev los txiav txim siab seb daim ntawv cog lus yog ionic lossis covalent. Los ntawm kev txhais, daim ntawv cog lus ionic yog nruab nrab ntawm cov hlau thiab cov hlau tsis muaj hlau, thiab covalent daim ntawv cog lus yog nruab nrab ntawm 2 nonmetals. Yog li koj feem ntau tsuas yog saib ntawm lub rooj zaum thiab txiav txim siab seb koj cov khoom puas yog ua los ntawm cov hlau / nonmetal lossis tsuas yog 2 nonmetals xwb
