Qhov sib txawv tseem ceeb ntawm cov ntsiab lus transuranic thiab cov xov tooj cua isotopes yog cov ntsiab lus transuranic yog cov tshuaj lom neeg muaj cov lej atomic ntau dua 92, hos radioisotopes tsis ruaj tsis khov atoms uas yog radioactive.
Ob lub ntsiab lus transuranic thiab cov xov tooj cua isotopes yog cov khoom siv hluav taws xob. Feem ntau, cov xov tooj cua atoms muaj tus lej atomic siab, tab sis qee zaum kuj muaj cov isotopes tsawg ntawm qee cov tshuaj lom neeg uas muaj tus lej atomic me, uas yog cov xov tooj cua vim qhov tsis sib xws ntawm protons thiab neutrons hauv lawv cov nuclei.
Dab tsi yog Transuranic Elements?
Transuranic cov ntsiab lus lossis cov ntsiab lus transuranium yog cov tshuaj lom neeg muaj cov lej atomic siab dua 92. Tus naj npawb atomic ntawm Uranium yog 92; Yog li ntawd, series ntawm transuranic ntsiab pib nrog Uranium, uas coj lub npe ntawm no series (trans + uranium). Tag nrho cov tswv cuab ntawm cov npe no yog cov xov tooj cua vim lawv qhov xwm txheej tsis ruaj khov.
Feem ntau ntawm cov tshuaj nyob rau hauv lub sij hawm lub sij hawm muaj isotopes peb yuav nrhiav tau nyob rau hauv lub ntug raws li ib tug ruaj khov atoms los yog raws li cov tshuaj muaj ib tug ntev ib nrab-lub neej. Cov tshuaj no muaj nyob rau hauv thaj tsam ntawm 1 txog 92 tus lej atomic.
Daim duab 01: Transuranic Elements
Peb tuaj yeem tsim cov ntsiab lus transuranic los ntawm kev siv cov khoom hluavtaws, siv cov tshuab hluav taws xob nuclear lossis siv cov khoom siv accelerators. Muaj kev sib raug zoo ntawm tus lej atomic thiab ib nrab-lub neej ntawm cov ntsiab lus no. Ib nrab-lub neej feem ntau txo qis nrog cov lej atomic. Txawm li cas los xij, tuaj yeem muaj qee qhov kev zam vim qee qhov isotopes; Piv txwv li, isotopes ntawm Curium thiab Dubnium.

Radioisotopes yog dab tsi?
Radioisotopes yog cov xov tooj cua isotopes ntawm cov tshuaj lom neeg. Cov isotopes no tsis ruaj khov vim tias lawv muaj ntau lub zog nuclear. Muaj peb txoj hauv kev uas lub xov tooj cua isotope tso tawm lub zog nuclear no:
- As gamma hluav taws xob
- Tshuaj ib qho kev hloov pauv hluav taws xob
- Alpha lossis beta particle emission
Yog tias ib qho ntawm peb qhov ua haujlwm saum toj no tshwm sim, peb hais tias cov xov tooj cua tawg tau tshwm sim. Peb lub npe cov emissions li ionizing hluav taws xob vim hais tias cov emission rays tuaj yeem ionize lwm lub atom kom dim ntawm electron.
Daim duab 02: Americium yog Radioisotope
Txhua yam tshuaj muaj nyob hauv cov khoom siv hluav taws xob hauv lawv cov ntawv isotopic. Piv txwv li, txawm lub lightest element hydrogen muaj ib tug radioactive isotope - tritium. Ntxiv mus, qee cov tshuaj muaj nyob tsuas yog cov khoom siv hluav taws xob xwb.
Qhov txawv ntawm Transuranic Elements thiab Radioisotopes yog dab tsi?
Ob lub ntsiab lus transuranic thiab cov xov tooj cua isotopes yog cov khoom siv hluav taws xob. Qhov sib txawv tseem ceeb ntawm cov ntsiab lus transuranic thiab cov xov tooj cua isotopes yog tias cov ntsiab lus transuranic yog cov tshuaj lom neeg muaj cov lej atomic ntau dua 92, hos cov xov tooj cua isotopes tsis ruaj khov atoms uas yog cov xov tooj cua.
Tsis tas li ntawd, cov ntsiab lus transuranic tsuas muaj nyob raws li cov xov tooj cua atoms xwb, thaum cov xov tooj cua isotopes yog cov isotopes ntawm cov tshuaj uas muaj nyob hauv cov atoms radioactive. Piv txwv li, actinide series, transactinide series thiab cov ntsiab lus ntawm lub sijhawm 8 yog cov ntsiab lus transuranic. Tritium isotope ntawm hydrogen yog ib lub teeb heev radioisotope nrog tus lej atomic tsawg heev.
Hauv qab infographic qhia txog qhov sib txawv ntawm cov ntsiab lus transuranic thiab radioisotopes.
Summary – Transuranic Elements vs Radioisotopes
Ob lub ntsiab lus transuranic thiab cov xov tooj cua isotopes yog cov tshuaj siv hluav taws xob. Qhov sib txawv tseem ceeb ntawm cov ntsiab lus transuranic thiab cov xov tooj cua isotopes yog tias cov ntsiab lus transuranic yog cov tshuaj lom neeg muaj cov lej atomic ntau dua 92, hos cov xov tooj cua isotopes tsis ruaj khov atoms uas yog cov xov tooj cua.
