Oxygen muaj 8 electron --- 2 hauv thawj lub plhaub, thiab 6 hauv lub plhaub thib ob (yog li rau valence electrons).

Ib yam li ntawd, muaj pes tsawg tus tub ntxhais electrons muaj?

Qhov 2 electrons hauv 4s orbital 7 electrons hauv 3d yog valence electrons : tag nrho lwm tus yog tub ntxhais electrons.

Ib sab saum toj no, koj ua li cas txiav txim siab valence? Rau nruab nrab atoms, tus naj npawb ntawm valence electrons yog sib npaug rau lub atom lub ntsiab pawg naj npawb. Tus lej tseem ceeb ntawm ib lub caij tuaj yeem pom los ntawm nws kab ntawv ntawm lub sijhawm ua haujlwm. Piv txwv li, carbon yog nyob rau hauv pawg 4 thiab muaj 4 valence electrons. Oxygen yog nyob rau hauv pawg 6 thiab muaj 6 valence electrons.

Muaj pes tsawg electrons muaj oxygen?

Oxygen yog #8 nyob rau hauv lub sij hawm lub rooj. Ua ntej hluav taws xob plhaub tuaj yeem tuav 2 electrons ; thib ob, 8. Yog li ntawd, tawm ntawm 8 electrons , 2 mus rau thawj lub plhaub thiab 6 mus rau qhov thib ob; valence electrons yog cov nyob ntawm lub plhaub sab nraud (muaj qee qhov kev zam, tab sis lawv yog ntau ntxiv rau ntawm lub rooj).

titanium muaj pes tsawg core electrons?

Kab pib nrog H muaj n=1; lub row pib nrog Li muaj n = 2; thiab lwm yam. suav nrog ib kab ntawm sab laug muab tus naj npawb ntawm valence electrons . Titanium yog 4 yam los ntawm sab laug thiab muaj 4 valus electrons . Nws yog nyob rau hauv kab sib raug rau n = 4 soits electronic configuration raws li ib tug nruab nrab atom yog [Ar]4s24d ib2.
