Txhua lub plhaub tuaj yeem tsuas muaj ib tug taag naj npawb ntawm electrons: Thawj plhaub tau tuav mus txog ob lub electrons, qhov thib ob plhaub tau tuav mus txog yim (2 + 6) electrons, thib peb plhaub tau tuav mus txog 18 (2 + 6 + 10) thiab lwm yam. General formula yog qhov nth plhaub tau ntawm txoj cai tuav mus txog 2 (n2) electrons.

Tsis tas li ntawd, muaj pes tsawg tus electrons tuaj yeem tuav 5 Plhaub?

50 electrons

Ib yam li ntawd, muaj pes tsawg electrons tuaj yeem tuav lub plhaub thib rau? Lub plhaub thib 6 tuaj yeem tuav txog 2(6)² = 2(36) = 72 ib electron . Nyob rau hauv qhov tseeb, tsis muaj ib qho atoms ntawm lub periodic rooj uas muaj 50 electrons hauv lawv lub plhaub thib tsib (lossis ib qho uas muaj 72 ib electron nyob rau hauv lawv lub plhaub 6th, los yog 98 electron ua nyob rau hauv lawv lub plhaub 7th, thiab lwm yam)

Ua raws li qhov no, muaj pes tsawg tus valence electrons tuaj yeem tuav 4th Plhaub?

Electron shells Lub plhaub no tuaj yeem muaj qhov siab tshaj plaws ob tug electrons . Lub plhaub thib ob tuaj yeem tuav qhov siab tshaj plaws ntawm yim electrons. Thaum qhov no puv lawm, electrons nkag mus rau hauv lub plhaub thib peb, uas tseem tuav tau ntau tshaj yim electrons. Tom qab ntawd lub plhaub thib plaub pib sau.

Muaj pes tsawg electrons tuav 7th Plhaub?

Daim ntawv ceeb toom tias koj tuaj yeem yooj yim pom cov naj npawb ntawm cov hluav taws xob uas lub atom tuaj yeem ua rau ntawm lub plhaub tshwj xeeb, lossis qib zog, los ntawm kev siv qhov tseeb tias txhua lub orbital tuaj yeem tuav qhov siab tshaj plaws. ob tug electrons.
