Thaum thawj theem zog muaj 2 electrons , cov electrons tom ntej no mus rau theem ob lub zog kom txog rau thaum qib thib ob muaj 8 electron . Thaum lub zog thib ob muaj 8 electron , cov electrons tom ntej no mus rau qib peb lub zog kom txog rau thaum qib peb muaj 8 electron.
Tsis tas li ntawd, muaj pes tsawg electrons nyob rau hauv lub zog thib ob ntawm ib qho atom ntawm txhua lub caij phosphorus?
Yog li rau lub caij ntawm PHOSPHORUS, koj twb paub lawm tias tus naj npawb atomic qhia koj cov xov tooj ntawm electrons. Qhov ntawd txhais tau tias muaj 15 electrons nyob rau hauv ib tug phosphorus atom. Saib ntawm daim duab, koj pom muaj ob tug electrons hauv plhaub ib, yim hauv plhaub ob, thiab tsib hauv plhaub peb.
Kuj Paub, pes tsawg tus electrons rau txhua lub caij? Cov tus lej ntawm protons yog qhov tus lej atomic , thiab cov tus lej ntawm protons ntxiv rau neutrons yog qhov atomic pawg. Rau hydrogen, lub atomic loj yog 1 vim muaj ib tug proton thiab tsis muaj neutrons. Rau helium, nws yog 4: ob protons thiab ob neutrons.
2.1 Hluav taws xob , Protons, Neutrons, thiab Atoms.
| Element | Helium | |
|---|---|---|
| Cim | Nws | |
| Atomic No. | 2 | |
| Tus naj npawb ntawm cov hluav taws xob hauv txhua lub plhaub | Ua ntej | 2 |
Kuj tseem paub, muaj pes tsawg tus electrons nyob hauv qib 2nd zog?
Txhua lub plhaub tuaj yeem tsuas muaj tus lej tas li electrons : Thawj lub plhaub tuaj yeem tuav tau txog ob electrons , cov thib ob plhaub tuaj yeem tuav txog yim (2 + 6) electrons , lub plhaub thib peb tuaj yeem tuav txog 18 (2 + 6 + 10) thiab lwm yam.
Muaj pes tsawg electrons nyob rau hauv peb lub zog?
18 electrons
