Iodine inoshandisa magetsi here?

Iodine iminerari yakakosha kune hutano hwevanhu. Asi inewo zvinhu zvemagetsi here? Tsvaga zvimwe nezvenyaya iyi inonakidza mune ino post.

Iodine itema, inopenya, crystalline yakasimba pakamuri tembiricha uye kumanikidzwa. Inogovera nzvimbo kurudyi rweperiodic tafura nemamwe halogens. Iodine inoshandiswa mune zvakawanda zvakasiyana-siyana semunyu, ingi, catalysts, makemikari emifananidzo, uye maLCD.

Iodine haisi conductor yakanaka yemagetsi nekuti covalent bonds inobata maerekitironi ayo zvakasimba (zvisungo pakati pemaatomu maviri ayodhine anoumba iyodhine morekuru, I2). Iodine ine yakaderera electronegativity ose halogens.

Iodine ikemikari chinhu chinoonekwa sechisiri chesimbi uye chinowanikwa kunyanya kune dzimwe nzvimbo dzepasi, kusanganisira mumakungwa.

Ichi chinyorwa chichakuudza pamusoro pezvinhu zvakasiyana-siyana zveiodine uye kana zvichiita magetsi.

Sei ayodhini isiri conductor isina kunaka yemagetsi?

Iodine haifambisi magetsi nekuti molecule imwe neimwe inoumbwa nemaatomu maviri ayodhine akabatwa pamwechete necovalent bond isingagoni kunakidzwa zvekugona kufambisa simba remagetsi.

Ko conductivity yeiodine inoshanduka sei pakati pekuoma uye mvura?

Zvisinei, conductivity yayo haina kuchinja zvikuru pakati yakasimba uye mvura. Kunyangwe iyo iodine isiri yakanaka conductor, kuiwedzera kune zvimwe zvinhu kunoita kuti vave makondakita ari nani. Iodine monochloride inzira ine simba yekuita kuti kabhoni nanotube waya dzifambise magetsi zvirinani.

Chii chinonzi iodine mumvura?

Iodide ndiyo ionic fomu yeiodine. Iine mhosva isina kunaka, sehalogen. Iyo I- (electrolyte kana ion) iri mumvura ichaita kuti neimwe nzira mvura yakachena iite magetsi.

Ndeupi rudzi rwe insulator yakanakira iodine?

Kana iwe ukakwanisa kuwana iodine muchimiro chemvura, yaizova covalent. Covalent makomisheni ndiwo zvakare akanakisa insulators, saka haatendere magetsi kupfuura (izvo zvinoitika kana ions ichifamba).

Chii chinonzi iodine?

Pane tembiricha yemumba, elemental iodine itema yakasimba, inopenya uye yakaturikidzana. Muzvisikwa, dzimwe nguva inowanikwa sedombo kana mineral, asi kazhinji inenge iri mumhando ye iodide, anion (I-). Zvishoma zvishoma zvine njodzi, asi huwandu hune njodzi. Mune chimiro chayo chekutanga, iodine inokonzera maronda eganda, uye iodine gasi (I2) inogumbura maziso.

Kunyangwe iyo iodine inogona kunge isingaite senge fluorine, chlorine, kana bromine, ichiri kuumba makomisheni ane zvimwe zvinhu zvakawanda uye inoonekwa seyakaora. Iodine yakasimba isiri simbi asi ine zvimwe zvinhu zvesimbi (kunyanya kupenya kwayo kana kupenya kwayo). Iodine insulator, semamwe akawanda asiri masimbi, saka haifambisi kupisa kana magetsi zvakanaka.

Chokwadi nezve iodine

• Iodine yakasimba inoita kunge dema, asi iruvara rwebhuruu-violet rwakasvibira runoenderana neruvara rwegasi ayodhini, yepepuru.
• Iodine ndicho chinhu chinorema chinodiwa nezvinhu zvipenyu uye chimwe chezvishoma.
• Yakawanda yeiodine inogadzirwa gore negore inoshandiswa sechinhu chinowedzera mukudya kwemhuka.
• Kushandiswa kwekutanga kwemunyu we iodized kwaive kuMichigan muna 1924. Vanhu vaigara pedyo negungwa uye vaidya zvekudya zvemugungwa muUnited States vakagamuchira huwandu hwakakwana hweiodine kubva kune zvakatipoteredza. Asi pakupedzisira zvakaonekwa kuti kushayikwa kweiodine kunowedzera njodzi yegoiter uye yakawedzera thyroid gland muvanhu vanogara kumaruwa. Nyika kubva kuMakomo eRocky kuenda kuGreat Lakes uye kumadokero kweNew York yainzi "bhandi rezvirimwa".
• Thyroid hormone inokosha pakukura kwepfungwa uye mumuviri. Sezvo thyroid gland inoda ayodhini kuti ibudise hormone thyroxine, kushaikwa kweiodine asati aberekwa (kubva kuna amai) kana kuti panguva yehuduku kunogona kukonzera matambudziko epfungwa kana kukura kwemwana. Kushaikwa kweiodine ndicho chikonzero chinowanzo konzera kuremara kwepfungwa kunogona kugadziriswa. Izvi zvinonzi congenital hypothyroidism, zvinoreva kuti munhu haana kukwana hormone yethyroid kubva paakaberekwa.

Sezvauri kuona, ayodhini inokanganisa kondakita wemagetsi. Nekuda kweizvi, inoshandiswa mune dzakawanda mamiriro sechikamu cheasina magetsi conductor. Paunenge uchitsvaga chinhu chisina-conductive chemamiriro ezvinhu, unoda kuve nechokwadi kuti hachizovhiringidzi magetsi.

Tarisa zvimwe zvezvinyorwa zvedu pazasi.

• Sucrose inofambisa magetsi
• Nitrogen inofambisa magetsi
• Isopropyl alcohol inoitisa magetsi
