Ура́н (U, лат. Uranium; устар. название — ура́ний) — химический элемент 3-й группы (по устаревшей классификации — побочной подгруппы третьей группы, IIIB) седьмого периода периодической системы химических элементов Д. И. Менделеева, с атомным номером 92. Относится к семейству актиноидов. Простое вещество уран — слаборадиоактивный металл серебристо-белого цвета. Уран не имеет стабильных изотопов. Самыми распространёнными изотопами урана являются уран-238 (имеет 146 нейтронов, в природном уране составляет 99,3 %) и уран-235 (143 нейтрона, содержание в природном уране 0,7204 %).
