Qhov sib txawv tseem ceeb ntawm fluorine thiab fluoride yog tias fluorine yog nruab nrab thaum fluoride tsis zoo.
Cov ntsiab lus hauv lub rooj ntu tshwj tsis yog cov roj hluav taws xob tsis ruaj khov. Yog li ntawd, cov ntsiab lus sim ua kom hnov mob nrog lwm cov ntsiab lus kom tau txais cov roj hluav taws xob zoo hluav taws xob thiab ua tiav kev ruaj ntseg. Fluorine yog ib qho tseem ceeb uas yuav tsum tau txais ib qho hluav taws xob kom ua tiav cov khoom siv hluav taws xob ntawm cov pa roj, neon. Tag nrho cov hlau reacts nrog fluorine, tsim fluorides. Yog li ntawd, muaj qhov sib txawv ntawm fluorine thiab fluoride nyob ntawm lawv lub cev thiab tshuaj lom neeg vim qhov hloov ntawm ib qho hluav taws xob.
fluorine yog dab tsi?
Fluorine yog ib qho khoom nyob rau hauv lub sij hawm lub sij hawm, uas yog denoted los ntawm F. Nws yog ib tug halogen (17th pawg) nyob rau hauv lub thib ob lub sij hawm ntawm lub periodic table. Tus naj npawb atomic ntawm fluorine yog 9; Yog li, nws muaj cuaj protons thiab cuaj electrons. Nws txoj kev teeb tsa hluav taws xob tau sau ua 1s2 2s2 2p5 Vim p sublevel yuav tsum muaj 6 electrons. kom tau txais Neon, noble gas electron configuration, fluorine muaj peev xwm nyiam ib tug electron. Raws li Pauling scale, Fluorine muaj lub siab tshaj plaws electronegativity nyob rau hauv lub periodic rooj, uas yog hais txog 4.
Daim duab 01: Fluorine Atom
Cov atomic loj ntawm fluorine yog 18.9984 amu. Nyob rau hauv chav tsev kub, fluorine muaj raws li ib tug diatomic molecule (F2). F2 yog xim daj daj-ntsuab xim roj thiab nws muaj qhov kub ntawm -219 ° C thiab qhov kub ntawm -188 ° C. Ntawm cov isotopes ntawm fluorine, F-17 tsis yog ib qho isotope ruaj khov thiab nws muaj ib nrab-lub neej ntawm 1.8 teev. Tab sis F-19 yog ib qho isotope ruaj khov. Kev nplua nuj ntawm F-19 hauv ntiaj teb yog 100%. Fluorine tuaj yeem oxidize oxygen thiab nws lub xeev oxidation yog -1.
fluorine gas yog denser dua huab cua thiab nws tuaj yeem ua kua thiab ua kom khov. Nws yog reactive heev, thiab qhov no yog vim nws high electronegativity thiab tsis muaj zog fluorine- fluorine daim ntawv cog lus. Ntxiv mus, cov tshuaj tiv thaiv ntawm hom tshuaj no nrog rau feem ntau ntawm lwm cov molecules yog ceev. Vim yog qhov reactivity, nws tsis pom raws li lub caij dawb.
fluoride yog dab tsi?
Fluoride yog cov anion uas tsim thaum fluorine abstracts ib qho hluav taws xob los ntawm lwm cov khoom electropositive. Peb tuaj yeem sawv cev nws los ntawm lub cim F-. Nws yog monovalent ion nrog -1 nqi. Yog li ntawd, nws muaj 10 electrons thiab cuaj protons. Ntxiv mus, lub teeb tsa hluav taws xob ntawm fluoride yog 1s2 2s2 26
Daim duab 02: Cov tshuaj txhuam hniav muaj fluoride
Fluoride muaj nyob rau hauv ionic compounds xws li sodium fluoride, calcium fluoride (fluorite) thiab HF. Nws kuj tshwm sim nyob rau hauv cov dej. Nws paub tias cov ion no pab tiv thaiv cov hniav lwj; yog li ntawd, nws muab ntxiv rau cov tshuaj txhuam hniav.
Qhov txawv ntawm Fluorine thiab Fluoride yog dab tsi?
fluorine yog cov tshuaj lom neeg thaum fluoride yog anion nws tsim. Qhov sib txawv tseem ceeb ntawm fluorine thiab fluoride yog tias fluorine yog nruab nrab thaum fluoride tsis zoo. Fluorine yog ib yam khoom nyob rau hauv lub sij hawm lub sij hawm uas yog denoted los ntawm F thaum fluoride yog anion muaj lub cim F-. Tsis tas li ntawd, tsis muaj cov khoom siv hluav taws xob tsis sib xws hauv fluoride, tab sis muaj ib qho hluav taws xob tsis sib xws hauv fluorine atom. Lwm qhov sib txawv ntawm fluorine thiab fluoride yog tias cov khoom tsis muaj fluorine tsis tshwm sim, tab sis fluoride ib txwm tshwm sim hauv cov dej.
Summary – Fluorine vs Fluoride
Yeej, fluorine yog cov tshuaj lom neeg thaum fluoride yog cov anion uas nws tsim. Qhov sib txawv tseem ceeb ntawm fluorine thiab fluoride yog tias fluorine yog nruab nrab thaum fluoride tsis raug nqi.
