29
Tsis tas li ntawd, muaj pes tsawg protons neutrons thiab electrons muaj tooj liab?
Tooj liab muaj tus lej atomic ntawm 29 , yog li nws muaj 29 proton thiab 29 electrons. Qhov hnyav atomic (tej zaum hu ua atomic mass) ntawm ib lub atom yog kwv yees los ntawm cov lej ntawm cov protons thiab cov naj npawb ntawm cov neutrons hauv lub nucleus ntawm lub atom.
Dab tsi yog qhov particle suav ntawm protons rau isotope Cu 64? Tooj , piv txwv li, muaj ob isotopes , tooj liab -63 thiab tooj liab -65. Tooj -63: 29 ib protons thiab ib pawg tus lej ntawm 63. Tooj -65: 29: kuv protons thiab pawg tus lej 65. Helium muaj 2 protons thiab yuav luag ib txwm muaj ib pawg tus lej ntawm 4.
Ib yam li ntawd, nws nug, tus naj npawb ntawm tooj liab yog dab tsi?
29
Dab tsi yog electron ntawm tooj liab?
Zoo, ua ntej, Tooj muaj 29 electrons thiab 29 protons, thiab nyob rau hauv qhov nws muaj ob isotopes. Hluav taws xob rau Qib Zog: 2, 8, 18, 1.

Tus naj npawb ntawm valence electrons hauv txhuas yog dab tsi?
plaub Dhau li ntawm no, koj ua li cas txiav txim seb tus naj npawb ntawm valence electrons? Rau nruab nrab atoms, lub tus naj npawb ntawm valenceelectrons yog sib npaug rau cov atom lub ntsiab pawg tus lej . Pab pawg tseem ceeb tus lej rau ib lub caij tuaj yeem pom los ntawm nws cov kab hauv lub rooj zaum.
Dab tsi yog tus naj npawb ntawm subatomic hais hauv atom ntawm B11?
Tom qab ntawd tus lej loj yog tag nrho cov protons ntxiv rau neutrons. Rau boron-11 tag nrho cov no yog 11, thiab tsib ntawm cov hais yog protons, yog li 11− 5 = 6 neutrons
Yuav ua li cas koj paub tus naj npawb ntawm protons hauv ib lub atom?
Tus naj npawb ntawm protons, neutrons, thiab electrons hauv atom tuaj yeem txiav txim siab los ntawm cov txheej txheem yooj yim. Tus naj npawb ntawm protons nyob rau hauv lub nucleus ntawm lub atom yog sib npaug rau atomic tooj (Z). Tus naj npawb ntawm electrons nyob rau hauv ib tug nruab nrab atom yog sib npaug zos rau tus naj npawb ntawm protons
Dab tsi yog tus naj npawb ntawm protons hauv atom ntawm silicon nrog cov lej loj tshaj plaws?
Piv txwv li, silicon muaj 14 protons thiab 14 neutrons. Nws atomic tooj yog 14 thiab nws atomic mass yog 28. Qhov feem ntau isotope ntawm uranium muaj 92 protons thiab 146 neutrons. Nws atomic tooj yog 92 thiab nws atomic mass yog 238 (92 + 146). 2.1 Electrons, Protons, Neutrons, thiab Atoms. Element Iron Symbol Fe Number of Electrons in Txhua Plhaub Thawj 2 Thib Ob 8 Peb 14
