Yog li nws cov atoms muaj 3 protons. Lub atom nruab nrab muaj qhov sib npaug ntawm cov protons thiab electrons, yog li lub nruab nrab Li atom kuj muaj 3 electron . Kev teeb tsa hluav taws xob ntawm Li yog 1s22s1. Yog li koj tuaj yeem pom tias muaj 2 sab hauv electrons hauv 1s sublevel.

Tsis tas li lo lus nug yog, pes tsawg tus electrons puas Li atom muaj nyob hauv 2s orbital?

Lithium yog qhov thib peb nrog tag nrho ntawm 3 electrons. Nyob rau hauv kev sau ntawv lub electron configuration rau lithium thawj ob tug electrons yuav mus nyob rau 1s orbital. Txij li 1s tuaj yeem tuav tau ob tug electrons qhov seem electron rau Li mus rau hauv 2s orbital. Yog li, Li electron configuration yuav yog 1s²2s ib¹.

Tsis tas li ntawd, muaj pes tsawg electrons nyob rau hauv lub zog thib ob ntawm lithium? 8 electron

Ntawm no, muaj pes tsawg electrons nyob hauv Li?

2, 1

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. Rau kev piav qhia vim li cas electrons muaj nyob hauv cov no plhaub saib electron configuration.
