Fluorine yog cov khoom siv tshuaj nrog lub cim F thiab atomic naj npawb 9. Nws yog lub teeb tshaj plaws halogen thiab muaj nyob rau ntawm cov txheej txheem raws li cov pa phem heev, daj ntseg daj diatomic gas. Raws li cov khoom siv electronegative tshaj plaws, nws yog qhov tsis tshua muaj tshwm sim, vim nws hnov qab tag nrho lwm cov ntsiab lus, tshwj tsis yog argon, neon, thiab helium.
Atoms ntawm fluorine yog dab tsi?
Fluorine (F), feem ntau cov tshuaj reactive thiab cov tswvcuab lub teeb tshaj plaws ntawm cov ntsiab lus halogen, lossis Pawg 17 (Pab pawg VIIa) ntawm lub sijhawm teem sijhawm. Nws cov tshuaj lom neeg muaj peev xwm raug ntaus nqi rau nws qhov muaj peev xwm txaus nyiam cov khoom siv hluav taws xob (nws yog cov khoom siv hluav taws xob feem ntau) thiab rau qhov me me ntawm nws cov atoms.
Puas muaj pes tsawg lub voj voog nyob hauv ib lub atom ntawm fluorine?
Qhov ntawd txhais tau tias muaj 9 electrons nyob rau hauv fluorine atom. Saib ntawm daim duab, koj tuaj yeem pom muaj ob lub electrons hauv plhaub ib thiab xya hauv plhaub ob. ► Xav paub ntau ntxiv txog keeb kwm thiab qhov chaw nrhiav fluorine.
Tus nqi ntawm ib qho atom ntawm fluorine yog dab tsi?
Ib fluorine atom muaj cuaj protons thiab cuaj electrons, yog li nws yog hluav taws xob nruab nrab. Yog hais tias fluorine atom tau txais ib qho hluav taws xob, nws dhau los ua cov fluoride ion nrog cov nqi hluav taws xob ntawm - 1.
Puas muaj pes tsawg neutrons nyob hauv fluorine atom?
Yog vim li cas:
Xav txog fluorine atoms nrog 9 protons thiab 10 neutrons.
