n.Symbol Mn （名詞）符號(hào) Mn
A gray-white or silvery brittle metallic element, occurring in several allotropic forms, found worldwide, especially in the ores pyrolusite and rhodochrosite and in nodules on the ocean floor. It is alloyed with steel to increase strength, hardness, wear resistance, and other properties and with other metals to form highly ferromagnetic materials. Atomic number 25; atomic weight 54.9380; melting point ,244=C; boiling point ,9'2=C; specific gravity 7.2 to 7.44; valence , 2, 3, 4, ', 7.See table at element
錳：一種呈灰白色或銀白色的易脆金屬，產(chǎn)生于幾種同素異形體中，世界各地均有，尤其盛產(chǎn)于軟錳礦、菱錳礦和海底的結(jié)核中。它與鋼的合金可增加強(qiáng)力、硬度、抗腐蝕力以及其它特性；與其它金屬可以合成高鐵磁性的材料。原子序數(shù)為25；原子量54.9380；熔點(diǎn),224=C；沸點(diǎn),9'2=C；比重7.2至7.44；化合價(jià)為,2,3,4,',7參見 element
