Hydrogen muaj 1 electron nyob rau hauv thawj lub plhaub (yog li ib valence electron ). Helium muaj 2 electrons --- ob qho tib si hauv thawj lub plhaub (yog li ob lub valence electrons). Lithium muaj 3 electrons --- 2 hauv thawj lub plhaub, thiab 1 hauv lub plhaub thib ob (yog li ib valence electron ).
Kuj tseem paub yog, lithium puas muaj valence electrons?
Lithium muaj atomic naj npawb ntawm 3. Yog li ib tug nruab nrab lithium atom muaj 3 protons thiab 3 electrons . Ob electrons hauv kab 1 thiab ib hluav taws xob hauv plhaub 2. Yog li Lithium muaj tsuas yog 1 valence electron hauv 2s orbital.
Ib yam li ntawd, pes tsawg neutrons nyob hauv lithium? 3
Ib yam li ib tug yuav nug, vim li cas 3rd plhaub 8 lossis 18?
Txhua plhaub muaj peev xwm tsuas muaj ib tug taag naj npawb ntawm electrons: Thawj plhaub tuaj yeem tuav tau txog li ob lub electrons, qhov thib ob plhaub tuaj yeem tuav tau yim (2 + 6) electrons, cov peb lub plhaub tuaj yeem tuav tau 18 (2 + 6 + 10) thiab lwm yam.
