Yog li, thaum koj tsiv mus nqes ib pab nyob rau hauv daim ntawv periodic, lub electronegativity ntawm ib qho kev txo qis vim tias qhov nce ntawm lub zog ua rau cov hluav taws xob sab nraud kom deb ntawm qhov rub ntawm lub nucleus. Electronegativity nce thaum koj txav ntawm sab laug mus rau sab xis hla ib lub sij hawm ntawm lub sij hawm.

Hais txog qhov no, vim li cas electronegativity txo qis hauv ib pawg?

Electronegativity . Txav mus rau hauv a pab pawg , cov electronegativity txo vim qhov deb ntawm lub nucleus thiab valence electron plhaub, yog li txo qhov attraction, ua rau lub atom muaj tsawg ntawm ib tug attraction rau electrons los yog protons.

Tom qab, lo lus nug yog, puas electronegativity muaj qhov sib txawv? Qhov siab dua electronegativity ntawm ib qho atom, qhov ntau dua nws lub peev xwm los nyiam sib koom electrons. Cov electronegativity ntawm atoms nce thaum koj txav ntawm sab laug mus rau sab xis hla ib lub sij hawm nyob rau hauv lub sij hawm. Cov electronegativity ntawm atoms txo qis thaum koj txav los ntawm sab saum toj mus rau hauv qab hauv ib pab pawg hauv lub sijhawm.

Ib tug kuj yuav nug, dab tsi yog qhov sib txawv ntawm ionization zog mus rau ib pawg?

Txav mus rau sab laug mus rau sab xis hla ib lub sijhawm, atomic radius txo qis, yog li cov hluav taws xob nyiam ntau dua rau (ze dua) nucleus. Tus general sib yog rau ionization zog kom txo qhov txav ntawm sab saum toj mus rau hauv qab nqes ib daim ntawv periodic pab pawg . Tsiv nqes ib pab , ib lub plhaub valence ntxiv.

Dab tsi yog qhov sib txawv ntawm tus lej atomic mus rau ib pawg?

- Cov tus lej ntawm qib zog nce thaum koj txav mus nqis ib pab raws li cov tus lej ntawm electrons nce. Txhua qib zog tom ntej yog ntxiv los ntawm cov nucleus tshaj qhov kawg. Yog li ntawd, lub atomic radius nce raws li qhov pab pawg thiab qib zog nce. 2) Thaum koj tsiv mus nyob ib ntus, atomic hluav taws xob txo.
