Ununoctium yog qhov hnyav tshaj plaws keeb , tab sis nws yog neeg tsim. Qhov hnyav tshaj plaws tshwm sim keeb yog uranium ( atomic num 92, atomic luj 238.0289).
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov siab tshaj plaws atomic naj npawb?
Txog tam sim no nws tau raug pov thawj tias nws yog tsawg kawg yog 118.
Ib yam li ntawd, lub ntsiab lus twg muaj atomic loj ntawm 12? Chemistry: List of Periodic Table Elements Sorted by: Atomic number
| Tsis muaj. | Atomic hnyav | Lub npe |
|---|---|---|
| 11 | 22.990 | Sodium |
| 12 | 24.305 | Magnesium |
| 13 | 26.982 | Aluminium |
| 14 | 28.086 | Silicon |
Ua kom pom qhov no, dab tsi yog qhov atomic loj ntawm tag nrho cov ntsiab lus?
Cov atomic loj ntawm ib keeb yog qhov nruab nrab pawg ntawm atoms ntawm ib keeb ntsuas hauv atomic loj unit (amu, tseem hu ua daltons, D). Cov atomic loj yog qhov hnyav nruab nrab ntawm tag nrho ntawm cov isotopes ntawm qhov ntawd keeb , hauv cov pawg ntawm txhua tus isotope yog muab faib los ntawm kev nplua nuj ntawm cov isotope tshwj xeeb.
Tus lej ntawm tag nrho cov ntsiab lus yog dab tsi?
Cov pawg naj npawb (sawv cev los ntawm tsab ntawv A) txhais tau tias yog tag nrho tus lej ntawm protons thiab neutrons nyob rau hauv ib tug atom. Xav txog cov lus hauv qab no, uas qhia cov ntaub ntawv los ntawm thawj rau rau cov ntsiab lus ntawm daim ntawv periodic. Xav txog qhov keeb helium. Nws atomic tus lej yog 2, yog li nws muaj ob lub protons hauv nws cov nucleus.
