Qhov sib txawv tseem ceeb ntawm bromine thiab iodine yog tias bromine nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub whereas iodine yog nyob rau hauv lub solid state.
Bromine thiab iodine yog cov ntsiab lus hauv pawg halide lossis pawg 17 ntawm lub sijhawm teem sijhawm. Yog li, ob lub ntsiab lus no muaj 7 electrons nyob rau hauv lawv lub plhaub sab nraud.
Bromine yog dab tsi?
Bromine, txhais los ntawm Br, yog halide muaj tus lej atomic 35. Thiab nyob rau hauv chav tsev kub, nws yog ib tug brownish-liab kua. Nws cov vapor kuj yog xim av xim av thiab muaj ntxhiab tsw ntxhiab. Ntxiv mus, nws yog tib yam nonmetal uas yog nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub. Cov kua no muaj Br2 molecules. Tsis tas li ntawd, nws yog tshuaj lom neeg tsawg dua li cov tshuaj chlorine thiab fluorine tab sis muaj ntau dua reactive dua iodine.

Daim duab 1: Bromine hauv lub Vial ruaj ntseg
Bromine yog ib txwm tshwm sim tsis yog hlau thiab muaj nyob rau hauv bromine-nplua nuj brine deposits nyob rau hauv lub teb chaws xws li teb chaws USA thiab Tuam Tshoj. Electrolysis yog ib txoj hauv kev uas tau txais los ntawm cov khoom no los ntawm cov brine deposits. Bromine yog thawj lub ntsiab tau muab rho tawm los ntawm dej hiav txwv. Txawm li cas los xij, nws tsis yog ib txoj hauv kev nrov niaj hnub no.
Iodine yog dab tsi?
Iodine (I) yog ib qho halide uas muaj tus lej atomic 53. Thiab nws nyob hauv lub xeev khov ntawm chav tsev kub thiab siab. Tsis tas li ntawd, nws yog nonmetal nyob rau hauv p block ntawm lub sij hawm lub sij hawm ntawm lub ntsiab lus.

Daim duab 2: Iodine Crystals
Txawm hais tias nws yog ib qho ci dub siv lead ua nyob rau hauv chav tsev kub, iodine tsim cov violet vapor thaum boiled. Ntxiv mus, cov crystals no tsawg soluble nyob rau hauv dej tab sis yog heev soluble nyob rau hauv nonpolar solvents xws li hexane.
Iodine muaj nyob rau hauv dej hiav txwv nyob rau hauv daim ntawv ntawm iodide ion (I
–) tab sis nyob rau hauv kab. Tam sim no, iodine minerals thiab natural brine deposits yog qhov feem ntau ntawm iodine.
Dab tsi zoo sib xws ntawm Bromine thiab iodine?
- Ob leeg Bromine thiab Iodine yog nonmetals.
- Kuj, ob leeg yog halogens.
- Ntxiv mus, ob qho tib si yog p thaiv cov ntsiab lus ib yam nkaus.
- Ob lub ntsiab yog tsim los ntawm xya valence electrons.
- Ob leeg muaj -1 stale oxidation xeev.
- Lawv ob leeg tsis muaj zog dua li cov tshuaj chlorine thiab fluorine.
