APAKAH MAKSUD TECHNETIUM dalam CORSICA?
Technetium
Technetium adalah unsur kimia dengan nombor atom 43 dan simbol Tc. Ia adalah unsur nombor atom terendah tanpa sebarang isotop stabil; setiap bentuknya adalah radioaktif. Hampir semua technetium dihasilkan secara sintetik, dan hanya jumlah minit yang terdapat dalam alam semula jadi. Technetium yang berlaku secara semulajadi berlaku sebagai produk fisi spontan dalam bijih uranium atau oleh penangkapan neutron dalam bijih molibdenum. Sifat-sifat kimia logam peralihan kelabu keperakan, adalah perantaraan antara rhenium dan mangan. Banyak sifat technetium yang diramalkan oleh Dmitri Mendeleev sebelum elemen itu ditemui. Mendeleev menyatakan jurang dalam jadual berkala dan memberikan unsur yang belum ditemui nama ekamangan itu. Pada tahun 1937, technetium menjadi elemen buatan pertama yang dihasilkan, oleh itu namanya. Gamma jangka pendek yang memancarkan isomer-technetium-99m nuklear digunakan dalam ubat nuklear untuk pelbagai ujian diagnostik. Technetium-99 digunakan sebagai sumber ray bebas beta gamma.
Definisi technetium dalam kamus Corsica
Pengertian technetium dalam kamus adalah unsur metalik yang berwarna abu-abu, yang dihasilkan secara buatan oleh pengeboman molibdenum oleh deuterons: digunakan untuk menghalang kakisan dalam keluli. Radionetotope technetium-99m, dengan separuh hayat enam jam, digunakan dalam radioterapi. Simbol: Tc; atom tidak: 43; separuh hayat isotop paling stabil, 97Tc: 2.6 × 106 tahun; valensi: 0, 2, 4, 5, 6, atau 7; ketumpatan relatif: 11.50; lebur pt: 2204 ° C; mendidih pt: 4265 ° C.
