Muaj 18 protons los ntawm cov argon Element. Nws 18 electrons vim yog nruab nrab , thiab 22 neutrons vim 40 - 18 = 22.
Tsuas yog li ntawd, pes tsawg protons nyob hauv AR 40?
Argon Nyob rau hauv cov huab cua muaj peb isotopes, tag nrho nrog 18 protons - tab sis ib hom (hu ua36 Ar ) muaj 18 neutrons thiab ib tug txheeb ze mass ntawm kwv yees li 36; hom thib ob (hu ua 38 Ar ) muaj 20 neutrons thiab ib tug txheeb ze pawg ntawm kwv yees li 38, thiab qhov kawg thiab feem ntau hom (hu ua 40Ar ) ib 22 neutrons thiab ib tug txheeb ze
Kuj Paub, puas yog atom nruab nrab? Cov nruab nrab Cov pa roj carbon atom muaj 6 electrons atomic tus lej yog 6 txij li ntawd yog 6 protons. Ntawm no, a " nruab nrab atom "yog ib qho yooj yim atom uas tsis muaj nqi. See, ib atom muaj cov protons, neutrons, andelectrons.
