Lub nucleus muaj ob hom subatomic hais, protons thiab neutrons. Cov protons muaj cov nqi hluav taws xob zoo thiab cov neutrons tsis muaj hluav taws xob. Ib hom thib peb ntawm subatomic particle,electrons, txav mus ncig lub nucleus. Cov hluav taws xob muaj hluav taws xob tsis zoo.
Koj hu li cas rau qhov tsis zoo nqi ntawm lub atom?
Electron: Ib qho teeb meem tsis zoo pom pom ncig los yog orbiting lub atomic nucleus. Ib tug electron, zoo li ib tug proton yog ib tug nqi particle, txawm hais tias opposite nyob rau hauv kos npe rau, tab sis tsis zoo li ib tug proton, ib tug electron muaj negligible atomic mass. … Qhov ntau electronegative ib atom, qhov nruj dua nws rub cov electrons.
Dab tsi yog qhov tsis zoo hauv lub nucleus?
Atomic Particles
Lub nucleus (center) ntawm atom muaj cov protons (zoo them) thiab cov neutrons (tsis them nqi). Cov cheeb tsam sab nraud ntawm lub atom yog hu ua electron shells thiab muaj cov electrons (negatively charged).
Yuav ua li cas thaum lub atom ua tsis zoo?
Yog tias ib lub atom muaj tus lej sib npaug ntawm cov protons thiab electrons, nws tus nqi them yog 0. Yog tias nws tau txais ib qho hluav taws xob ntxiv, nws yuavtsis zoo them thiab paub tias yog anion. Yog tias nws poob ib qho hluav taws xob, nws yuav raug them zoo thiab paub tias yog cation.
Yuav ua li cas cov khoom ua tsis zoo?
Cov electron nqa cov nqi tsis zoo (−1.602 ×10−19 Coulombs). Lub atom hu ua nruab nrab yog tias tus naj npawb ntawm protons sib npaug ntawm cov electrons. … Cov particle uas raug them yog qhov tsis zoo thaum nws nce electron los ntawm lwm lub atom. Nws raug nqi zoo yog tias nws poob hluav taws xob los ntawm nws.
