Atoms muaj negatively charged electrons thiab zoo them protons; tus lej ntawm txhua tus txiav txim siab tus nqi ntawm atom.
Atom puas tuaj yeem them nqi zoo?
Txhua qhov hais, txawm tias ib qho atom, molecule lossis ion, uas muaj cov hluav taws xob tsawg dua li cov protonstau hais kom them nyiaj zoo. Hloov pauv, txhua qhov khoom uas muaj cov khoom siv hluav taws xob ntau dua li cov protons tau hais tias raug nqi tsis zoo.
Yuav ua li cas tsis zoo lossis raug nqi?
Inside ib atom yog protons, electrons thiab neutrons. Cov protons raug them zoo, cov electrons raug them tsis zoo, thiab cov neutrons yog nruab nrab. Yog li ntawd, txhua yam yog tsim los ntawm tus nqi. Cov nqi sib tw sib nyiam (tsis zoo rau qhov zoo).
Puas yog tus nqi zoo?
Proton-positive; electron-negative; neutron-tsis muaj nqi. Tus nqi ntawm cov proton thiab electron yog tib yam loj tab sis txawv. Tib tus naj npawb ntawm protons thiab electrons raws nraim tshem tawm ib leeg hauv ib qho nruab nrab atom. … Nws kuj qhia tau hais tias tus naj npawb ntawm electrons yog tib yam li tus naj npawb ntawm protons.
Yog tus nqi tsis zoo?
Tus nqi tsis zoo yog cov khoom hluav taws xob ntawm cov khoom ntawm cov nplai subatomic. Ib yam khoom raug them tsis zoo yog tias nws muaj ntau dhau ntawm electrons, thiab tsis raug them lossis raug them lwm yam zoo. Xws li electrochemical kev ua si plays lub luag haujlwm tseem ceeb hauvcorrosion thiab nws tiv thaiv.
