Hauv qhov no, qhov kev teeb tsa hluav taws xob ntawm qhov nruab nrab calcium atom yog dab tsi?

Cov atomic tus lej ntawm calcium yog 20. Qhov no txhais tau tias nyob rau hauv a nruab nrab calcium atom , muaj 20 protons hauv nws cov nucleus. A nruab nrab calcium atom tseem muaj 20 electrons . Cov electron configuration ntawm ib tug nruab nrab calcium atom yog 1s22s22p63s23p64s2.

Calcium atom yog dab tsi? Calcium yog ib yam tshuaj nyob rau hauv lub sij hawm uas muaj lub cim Ca thiab atomic num 20. Calcium yog ib tug mos grey alkaline ntiaj teb hlau uas yog siv los ua ib tug txo tus neeg sawv cev nyob rau hauv lub extraction ntawm thorium, zirconium thiab uranium. Lub caij no kuj yog lub thib tsib tshaj plaws nyob rau hauv lub ntiaj teb crust.

Hais txog qhov no, qhov kev teeb tsa hluav taws xob rau calcium atomic tooj 20 yog dab tsi?

Piv txwv li, hauv av xeev electronic configuration ntawm calcium (Z = 20 ) yog 1s 22s ib 22 ib p 63s ib 23 ua p 64s ib 2. Cov calcium ion ( Ca 2+), txawm li cas los xij, muaj ob electrons tsawg.

Lub caij twg muaj qhov zoo tshaj plaws electronegativity?

Electronegativity nce hauv qab mus rau sab saum toj hauv pab pawg, thiab nce los ntawm sab laug mus rau sab xis hla lub sijhawm. Yog li, tshuaj fluorine yog lub feem ntau electronegative keeb, thaum francium yog ib qho ntawm qhov tsawg tshaj plaws electronegative.
