Yog li ntawd, hauv poov tshuaj , lub sab nraud electron zoo dua tiv thaiv los ntawm lub zog txaus nyiam ntawm lub nucleus. Nws ua raws, yog li ntawd, qhov no sab nraud electron yog ntau yooj yim ploj tshaj nws yog nyob rau hauv sodium , yog li poov tshuaj tuaj yeem hloov mus rau ib daim ntawv ionic ntau npaj txhij dua li sodium . Vim li no, poov tshuaj yog ntau reactive tshaj sodium.

Ntawm no, vim li cas cov poov tshuaj ntau dua li sodium BBC Bitesize?

Potassium tarnishes sai heev uas nws nyuaj rau pom qhov ntawd potassium yog ua tau ib lub ci hlau. Qhov no yog pov thawj ntxiv tias potassium yog ib ntau reactive hlau tshaj lithium thiab lithium sodium.

Kuj Paub, vim li cas cov poov tshuaj ntau dua li magnesium? Sodium reacts los ntawm poob ib qho electron. Magnesium reacts los ntawm poob ob electrons. Ib yam li ntawd, atoms ntawm poov tshuaj (K hauv lub rooj) loj dua, thiab yog li ntawd ntau reactive , tshaj atom ntawm sodium. Nws ua raws cov ntsiab lus hauv qab no poov tshuaj nyob rau hauv lub rooj yuav tsum ntau reactive tshaj poov tshuaj yog.

Ib yam li ntawd, koj tuaj yeem nug, qhov twg yog cov hlau feem ntau cov tshuaj sodium lossis potassium?

Hauv tsev neeg alkali hlau, reactivity nce nrog nce tus lej atomic . Qhov no ua rau Francium reactive tshaj plaws, tom qab ntawd cesium, rubidium, potassium, sodium thiab lithium. Francium yuav luag tsis muaj nyob rau hauv cov xwm yog li cesium yog cov reactive hlau feem ntau ntawm cov pom.

Puas yog Na lossis K ntau dua?

Raws li ib feem ntawm cov alkali hlau pawg nyob rau hauv lub periodic rooj, sodium yog heev reactive thiab yeej tsis pom qhov ntshiab hauv qhov. Hauv cov hlau alkali, sodium yog ntau reactive tshaj lithium tab sis tsawg reactive tshaj poov tshuaj. Nws lub zog ionization yog siab dua cov poov tshuaj tab sis qis dua lithium.
