Ang uranyo o uranyum (Kastila: uranio, Ingles: uranium, may sagisag na U, atomikong bilang na 92, atomikong timbang na 238.03, punto ng pagkatunaw na 1,132 °C, punto ng pagkulong 3,818 °C, espesipikong grabidad na 18.95, mga balensiyang 3, 4, 5, at 6). Isa itong elementong mabigat, parang pilak ang kaputian, likas na radyoaktibo at parang metal, na madaling sumailalim sa oksidasyon, at nakakalason. Mayroon itong 14 na kilalang mga isotopo, kung saan ang U 238 ang siyang likas na pinakamalaganap. Kabilang ang uranyo sa mga serye ng aktinido at ginagamit ang kanyang isotopong ²³⁵U bilang panggatong na nukleyar, mga panggatong sa mga nukleyar reaktor, at bilang mahalagang sangkap ng mga sandatang nukleyar. Karaniwang matatagpuan ang uranyo sa maliit na bahagi sa mga bato, tubig, lupa, mga halaman, at mga hayop (kabilang ang mga tao). Natuklasan ito ni Martin Heinrich Klaproth noong 1789.^[8]

Talababa

↑ The thermal expansion is anisotropic: the coefficients for each crystal axis (at 20 °C) are α_a = 25.27×10⁻⁶/K, α_b = 0.76×10⁻⁶/K, α_c = 20.35×10⁻⁶/K, and α_average = α_volume/3 = 15.46×10⁻⁶/K.
