APAKAH MAKSUD IRIDIUM dalam CORSICA?

Iridium

Iridium

Iridium adalah unsur kimia dengan simbol Ir dan nombor atom 77. Sebuah logam peralihan yang sangat keras, rapuh, berwarna putih dari keluarga platinum, Iridium pada umumnya dikreditkan sebagai elemen terpadat kedua berdasarkan ketumpatan yang diukur, walaupun pengiraan yang melibatkan ruang kisi unsur-unsur menunjukkan bahawa iridium lebih padat, dan logam yang paling tahan karat, walaupun pada suhu setinggi 2000 ° C. Walaupun hanya beberapa garam cair dan halogen yang menghancurkan iridium pepejal, debu iridium yang dibahagi dengan halus adalah lebih reaktif dan boleh menjadi mudah terbakar. Iridium ditemui pada 1803 di antara kekotoran yang tidak larut dalam platinum semulajadi. Smithson Tennant, penemu utama, bernama iridium untuk dewi Yunani Iris, pengenalan pelangi, kerana warna yang menarik dan pelbagai garamnya. Iridium adalah salah satu unsur paling jarang dalam kerak Bumi, dengan pengeluaran tahunan dan penggunaan hanya tiga tan. 191Ir dan 193Ir adalah dua isotop semulajadi iridium, serta satu-satunya isotop yang stabil; yang terakhir adalah lebih banyak daripada kedua-dua mereka.

Iridium is the chemical element with symbol Ir and atomic number 77. A very hard, brittle, silvery-white transition metal of the platinum family, Iridium is generally credited with being the second densest element based on measured density, although calculations involving the space lattices of the elements show that iridium is denser, and is the most corrosion-resistant metal, even at temperatures as high as 2000 °C. Although only certain molten salts and halogens are corrosive to solid iridium, finely divided iridium dust is much more reactive and can be flammable. Iridium was discovered in 1803 among insoluble impurities in natural platinum. Smithson Tennant, the primary discoverer, named iridium for the Greek goddess Iris, personification of the rainbow, because of the striking and diverse colors of its salts. Iridium is one of the rarest elements in the Earth's crust, with annual production and consumption of only three tonnes. 191Ir and 193Ir are the only two naturally occurring isotopes of iridium, as well as the only stable isotopes; the latter is the more abundant of the two.
