补充资料:铁系元素
分子式:
CAS号:

性质:元素周期表中第8,9,10(VIIIB)族元素铁(Fe)、钴(Co)、镍(Ni)总称为铁系元素。他们的性质相似,都是银白色金属,熔点和沸点、原子半径、电离势等物理性质相近,都表现出明显的顺磁性,通常称为铁磁性物质。其外层电子组态为3d6~84s2,常见氧化态为+2,铁和钴还有+3。在碱性溶液中强氧化剂可将钴和镍氧化到+5和+4氧化态,铁到+6氧化态,以含氧酸盐或配盐形式存在。可溶于稀酸,在冷浓的硝酸和硫酸中,由于金属表面被钝化而不易溶解。在浓碱溶液中,铁被缓慢腐蚀,而钴、镍较稳定。在加热情况下,能与氧、硫、氯等非金属发生剧烈反应。三价铁、三价钴和三价镍的氧化性,按铁(III)<钴(III)<镍(III)的顺序增强。铁(III)、铁(II)、钴(II)、镍(II)的强酸盐几乎都溶于水。能与许多配体(CN-、ScN-、CO等)生成配位化合物,如K4[Fe(CN)6]、[Co(SCN)4]2+、Ni(CO4)等。
