What is Chromium in Chemistry


Chromium Chemical Element Information in Urdu/Hindi


Chromium aik chemical element hai periodic table jahan par tamam element ki list hoti hai wahan iska symbol  Cr hai. Chromium ke hamesha 24 protons hote hain isliye iska atomic number 24 hai. Chromium ka mass number yani isky Protons aur Neutrons ka number 54 hai. Chrome ke neutrons ziyada tar 28 hote hai lekin mukhtalif isotopes ziyada ya kam neutrons rakhte hain. Chromium aik metal ke taur par 24 electrons rakhta hai iskay ions mein kam electrons hote hain. Chromium aik shiny metal hai aur ye rad e amal karta hai lekin ye chromium(III) oxide ki bohat bareek coating banane ke liye hawa ke sath rad e amal karta hai jo isay zang lagne say bachata hai. Chromium ke compounds mukhtalif oxidation states mein zahir hota hai +2, +3, aur +6 bohat aam hai ye chemical compounds ki shakal banata hai jo rang wale hote hain.

Trivalent Chromium


What is Chromium Used for in The Human Body


Chromium ios ke 2 iqsam hain jo kay chromium compounds mein payi jati hain chromium ki aik type Cr trivalent chromium hai jiski humari jism ko zaroorat hoti hai aur dusry janwaron ko bhi iski zaroorat hoti hai. Agar humein chromium kafi hasil nahi hota to phir humare jism ke baaz hisay shayad sahi kaam na karen. Humain ziyada tar chromium humari khurak sey hasil ho jata hai. Chromium ko Vitamins mein isliye shamil kiya jata hai takay humare jism ko chromium ki kafi miqdar mile agar humare jism ko bohat ziyada chromium mil jata hai to ye humare jism ko nuqsan pohancha sakta hai.

Hexavalent Chromium


Chromium ki aik aur kisam Cr6+ chromate, hexavalent chromium +6 oxidation state jo kay cancer ki wajah ban sakti hai ya phir logon ko bimaar kar sakti hai agarcha ziyada tar logon ko iska samna na ho. Ye aisi jagah par paya jata hai jahan chromium metal tayar hota hai yehi wajah hai kay jab wo isay band karte hain to unhen saaf karne ki zarorat parti hai. Hexavalent chromium ko reducing agents ke rad e amal ke sath tabah kiya ja sakta hai jis say ye Cr3+ trivalent chromium ban jata hai ye taqatwar oxidizing agents hain.

Chromates


Chromates ion aik CrO42- chromates aam taur par peelay rang ke hote hain. Potassium chromate, sodium chromate.

Dichromates


Dichromates ka ion Cr2O72- dichromates laal aur maltay rang ke hote hain. Ammonium dichromate
Potassium dichromate Sodium dichromate ko chromium processing mein istemal kiya jata hai.

Chromium Occurrence and Preparation


Chromium chromite ke taur par zahir hota hai chromite iron(II) aur chromium(III) ka aik mixture hai. Iska chemical formula FeCr2O4 hai. Isay sodium carbonate ke sath sodium chromate, iron (III) oxide aur carbon dioxide banane ke liye garam kiya jata hai. Sodium chromate sodium dichromate banane ke liye sulfuric acid ke sath rad e amal karta hai. Sodium dichromate ko carbon ke zariye chromium (III) oxide ki taraf reduced kiya jata hai. Chromium oxide Aluminum ke sath chromium metal banane ke liye rad e amal zahir karta hai. Chromates aur dichromates chromium production ki jagah ko zehreela banate  hain.

Chromium Uses in Everyday Life



Chromium ko mukhtalif metal products mein istemal kiya jata hai. Stainless steel mein chrome ka istemal bohat aam hai. Ye chrome plating mein bhi istemal hota hai jiski wajah sey cheezon ko chamakdar banaya jata hai kuch chromates ko roghan karne ke liye istemal kiya jatay thy lekin ye zehreela hota hai isliye ab log mazeed iska istemal nahi karte. Chromium metal zehreela nahi hota lekin hexavalent chromium zehreela hota hai. Carcinogenic aur trivalent chromium agar zyada tadad mein hoon to ye halke sey zehreelay hote hain.
