Vim tias cov kev sib cuam tshuam no kuj tsis muaj zog, cov khoom molecular zoo li mos thiab muaj cov ntsiab lus melting tsawg mus rau nruab nrab. Molecular cov khoom tseem yog cov khoom siv hluav taws xob tsis zoovim tias lawv cov valence electrons raug kaw nruj nreem nyob hauv txhua tus molecule.
Puas molecular solid conductors zoo?
Molecular solids-Ua los ntawm atoms lossis molecules tuav ua ke los ntawm London dispersion rog, dipole-dipole rog, lossis hydrogen bonds. Cov yam ntxwv los ntawm cov ntsiab lus melting tsawg thiab yoog raws thiab yog tsis zoo conductors.
Puas molecular solids ua hluav taws xob dej?
Molecular solids yog tuav ua ke los ntawm covalent bonds uas cov atoms ntawm daim ntawv cog lus sib koom electrons. Vim tias lawv tab tom sib koom cov khoom siv hluav taws xob, tsis muaj qhov tsis sib haum ionic nqi los ua hluav taws xob tam sim no. Yog li ntawd txawm tias thaum dissolved hauv dej lawv yuav tsis ua hluav taws xob
Puas molecular covalent solids ua hluav taws xob?
Covalent compounds (khoom, kua, kua) tsis ua hluav taws xob Cov ntsiab lus hlau thiab carbon (graphite) yog cov hluav taws xob hluav taws xob tab sis cov khoom tsis yog hlau yog cov hluav taws xob hluav taws xob. Ionic bonds yog electrostatic attraction ntawm zoo thiab tsis zoo ions.
Vim li cas molecular solids hluav taws xob insulators?
Cov kuab tshuaj thiab cov khoom khib nyiab uas muaj cov molecules tau tuav ua ke los ntawm van der Waals (los yog intermolecular) rog, thiab ntau yam ntawm lawv cov khoom muaj kev cuam tshuam qhov kev khi tsis muaj zog. … Vim tias ntawm tus nqi nruab nrab ntawm cov khoom siv molecules, thiab vim qhov kev ncua deb ntawm lawv, molecular solids yog hluav taws xob insulators.
