Concentrated nyob rau hauv lub atomic center yog a cheeb tsam ntawm pawg qee zaum hu ua cov nucleus. (Hauv biology, lo lus nucleus muaj lwm lub ntsiab lus, yog li peb yuav hu qhov no cheeb tsam tus atomic center). Hauv no Central cheeb tsam yog cov protons thiab neutrons.
Hais txog qhov no, dab tsi yog qhov particle uas txav ib ncig ntawm lub hauv paus ntawm lub atom?
electrons
Ib yam li ntawd, leej twg hais tias lub nucleus nyob hauv nruab nrab ntawm lub atom? Ernest Rutherford
Ib yam li ntawd, tus qauv ntawm lub atom yog dab tsi?
Piav: Qhov yooj yim qauv ntawm lub atom suav nrog ib tug me me, kuj loj nucleus, muaj tsawg kawg yog ib tug proton thiab feem ntau yog ib los yog ntau tshaj neutrons. Sab nraud ntawm lub nucleus yog qib zog (tseem hu ua plhaub), uas muaj ib lossis ntau dua electrons. Cov electrons yuav luag tsis muaj huab hwm coj thiab raug them tsis zoo.
Dab tsi yog qhov chaw ntawm lub atom?
Peb cov qauv tam sim no ntawm atom tuaj yeem muab faib ua peb pawg ntu - protons, neutron, thiab electrons. Txhua yam ntawm no ntu muaj cov nqi sib txuas, nrog cov protons nqa cov nqi zoo, cov hluav taws xob muaj qhov tsis zoo, thiab cov neutrons tsis muaj nuj nqis.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Dab tsi yog meant los ntawm cheeb tsam ntawm lub voj voog?
Lub cheeb tsam ntawm lub voj voog yog tus naj npawb ntawm cov square units hauv lub voj voog. Yog hais tias txhua square nyob rau hauv lub voj voog mus rau sab laug muaj thaj tsam ntawm 1 cm2, koj tuaj yeem suav tag nrho cov squares kom tau thaj tsam ntawm lub voj voog no
Yuav ua li cas koj pom lub hauv paus cheeb tsam ntawm daim duab peb sab prism?
Ib daim duab peb sab prism muaj peb lub duab plaub sab thiab ob lub ntsej muag daim duab peb sab. Txhawm rau nrhiav thaj tsam ntawm lub kaum sab xis, siv tus qauv A = lw, qhov twg A = thaj tsam, l = ntev, thiab h = qhov siab. Txhawm rau nrhiav thaj tsam ntawm daim duab peb sab, siv cov qauv A = 1/2bh, qhov twg A = thaj tsam, b = puag, thiab h = qhov siab
