Cov cov khoom nquag tshaj plaws hauv Pawg 17 yog FLUORINE. Cov ntsiab lus hauv ib pab pawg muaj tus lej zoo sib xws ntawm VALENCE ELECTRONS. Cov ntsiab lus nyob rau hauv ib tug series muaj tib tus lej ntawm PRINCIPAL ENERGY LEVELS.
Yog li, dab tsi yog lub ntsiab lus tseem ceeb tshaj plaws hauv Pawg 17?
Teb. Electronegativity nce thoob plaws ib lub sijhawm, thiab txo qis a pab pawg . Yog li ntawd, fluorine muaj cov tshuaj siab tshaj electronegativity tawm ntawm tag nrho cov cov ntsiab lus . Vim tias fluorine muaj xya valence electrons, nws tsuas xav tau ib qho xwb ntau electron kom ua tiav qhov kev teeb tsa noble gas (yimvalence electrons).
Tom qab ntawd, lo lus nug yog, qhov twg yog cov khoom nquag tshaj plaws nyob hauv? Cov cov ntsiab lus mus rau hauv qab sab laug ces kaum ntawm lub sij hawm lub rooj yog cov hlau uas yog cov nquag nquag hauv kev nkag siab ntawm kev ua tus feem ntau reactive.
Yog li ntawd, cov ntsiab lus twg hauv Pawg 17 yog kua?
Pawg 17 Cov ntsiab lus. Cov pab pawg 17 muaj xws li fluorine (F), chlorine (Cl), bromine (Br), iodine (I) thiab astatin (Ntawm) los ntawm sab saum toj mus rau hauv qab. Lawv hu ua "halogens" vim tias lawv muab ntsev thaum lawv hnov mob nrog cov hlau.
Lub ntsiab lus twg ntawm pawg 17 muaj nyob hauv qhov khoom ntawm 25?
Cov halogens muaj nyob, nyob rau hauv chav tsev kub, nyob rau hauv tag nrho peb lub xeev ntawm teeb meem: Khoom - Iodine, Astatine. Kua- Bromine. Gas- Fluorine, Chlorine.
