Electronegativity yog ib tug txheeb ze scale. Thaum twg tshuaj fluorine reacts nrog hlau, nws oxidizes hlau, thiab daim ntawv ib ionic daim ntawv cog lus . Txawm li cas los xij, thaum ob tshuaj fluorine atoms teb rau daim ntawv tus tshuaj fluorine molecule, ib tug purely covalent daim ntawv cog lus yog tsim.

Ntawm no, hom ntawv cog lus twg yog fluorine thiab fluorine?

Nrog rau lwm cov atoms, tshuaj fluorine daim ntawv yog polarcovalent daim ntawv cog lus los yog ionic daim ntawv cog lus . Feem ntau, covalent daim ntawv cog lus koom nrog tshuaj fluorine atoms yog ib leeg daim ntawv cog lus , txawm tias tsawg kawg yog ob qho piv txwv ntawm kev txiav txim siab dua daim ntawv cog lus muaj. Fluoride tuaj yeem ua raws li kev sib txuas ntawm ligand nruab nrab ntawm ob cov hlau hauv qee cov molecules complex.

Tsis tas li ntawd, hom kev sib cog lus dab tsi tshwm sim ntawm lithium thiab fluorine? Sawv cev ntawm ionic bonding ntawm lithium thiab fluorine ua form lithium fluoride . Lithium muaj ionization zog thiab yooj yim muab nws ib leeg valenceelectron rau a tshuaj fluorine atom, uas muaj ib tug zoo electronaffinity thiab txais cov electron uas tau pub los ntawm lub lithium atom.

Xav txog qhov no, hom ntawv cog lus twg yuav tsim ntawm ob lub fluorine atoms?

Cov hom ntawv cog lus uas feem ntau yuav yog tsim ntawm ob lub fluorine atoms yog nonpolar covalent daim ntawv cog lus . Hluav taws xob nruab nrab tus ob fluorine atoms sib koom nruab nrab lawv.

Cov ntsiab lus dab tsi tuaj yeem sib txuas nrog fluorine?

Fluorine (F2), muaj ob tshuaj fluorine atoms, ua ke nrog tag nrho lwm yam cov ntsiab lus Tsuas yog helium thiab neon los tsim ionic lossis covalentfluorides.
