Magnesium yog cov khoom siv tshuaj nrog lub cim Mg thiab tus lej atomic 12. Nws yog cov khoom ci ntsa iab grey uas dais lub cev zoo ib yam li lwm tsib lub ntsiab lus hauv kab thib ob ntawm lub sijhawm …
Dab tsi yog kev sib txuas ntawm atomic radius?
Qhov kev ncua deb ntawm ob lub nuclei yog hu ua kev sib txuas ntawm atomic radius. • Nws luv dua lub vojvoog tsis sib txuas. • Yog tias ob lub atoms uas tsim cov molecule zoo ib yam, ces ib nrab ntawm daim ntawv cog lus deb yog hu ua covalent radius ntawm lub atom.
Tc 99 lwj mus ua dab tsi?
Technetium-99 (99 Tc) yog ib qho isotope ntawm technetium uas decays nrog ib nrab-lub neej ntawm 211,000 xyoo rau ruaj khov ruthenium-99, emitting beta hais, tab sis tsis muaj gamma rays.
Dab tsi yog qhov luaj li cas ntawm atomic radius?
Daim duab 1. Lub atomic radius (r) ntawm ib lub atom tuaj yeem txhais tau tias yog ib nrab ntawm qhov kev ncua deb (d) nruab nrab ntawm ob lub nuclei hauv diatomic molecule . Atomic radii tau ntsuas rau cov ntsiab lus. Cov units rau atomic radii yog picometers, sib npaug rau 10−12 meters.
Yuav daws li cas rau atomic radius?
Faib qhov kev ncua deb ntawm lub nuclei ntawm lub atom los ntawm ob yog tias daim ntawv cog lus yog covalent. Piv txwv li, yog tias koj paub qhov kev ncua deb ntawm lub nuclei ntawm ob lub atom sib raug zoo yog 100 picometers (pm), lub vojvoog ntawm txhua tus atom yog 50 teev tsaus ntuj.
