An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Few compounds of californium have been made and studied. The only californium ion that is stable in aqueous solutions is the californium(III) cation. The other two oxidation states are IV (strong oxidizing agents) and II (strong reducing agents). The element forms a water-soluble chloride, nitrate, perchlorate, and sulfate and is precipitated as a fluoride, oxalate or hydroxide. If problems of availability of the element could be overcome, then CfBr2 and CfI2 would likely be stable.

dbo:abstract
  • S'han fet i estudiat pocs compostos del californi. L'únic ió estable de californi en una solució aquosa és el catió californi (III). Els altres dos estats d'oxidació són el IV (fort agent oxidant) i el II (fort agent reductor). L'element forma clorur, nitrat, perclorat i sulfat solubles en aigua, i es precipita com un fluorur, oxalat o hidròxid. Si els problemes de disponibilitat de l'element es deixen de banda, llavors el CfBr₂ i el CfI₂ segurament serien estables. L'estat d'oxidació +3 està representat per l'òxid de californi (III) (groc-verd, Cf₂O₃), el fluorur de californi (III) (verd, CfF₃) i el iodur de californi (III) (groc llimona, CfI₃). Els altres estats d'oxidació +3 inclouen el sulfur i el metal·locè. L'òxid de californi (IV) (marró fosc, CfO₂) i el fluorur de californi (IV)) (verd, CfF₄) representen l'estat d'oxidació IV. L'estat d'oxidació II es troba representat pel bromur de californi (II) (groc, CfBr₂) i el iodur de californi (II) (violeta fosc, CfI₂). (ca)

If problems of availability of the element could be overcome, then CfBr2 and CfI2 would likely be stable. The +3 oxidation state is represented by californium(III) oxide (yellow-green, Cf2O3), californium(III) fluoride (bright green, CfF3) and californium(III) iodide (lemon yellow, CfI3). Other +3 oxidation states include the sulfide and metallocene. Californium(IV) oxide (black brown, CfO2), californium(IV) fluoride (green, CfF4) represent the IV oxidation state. The II state is represented by californium(II) bromide (yellow, CfBr2) and californium(II) iodide (dark violet, CfI2). (en)
  • 锎化合物是锎元素形成的化合物,只有很少一些有所研究。三氯化锎是最先发现的锎化合物,由伯里斯·坎宁安于1960年在劳伦斯伯克利国家实验室制备出来。唯一能在水溶液稳定的离子是三价的锎离子,而二价的具有强还原性,四价的具有强氧化性。锎的氯化物、硝酸盐、硫酸盐和高氯酸盐都是可溶的,而氟化物、氢氧化物和草酸盐是难溶的。 锎的+3价态的代表的三氧化二锎(黄绿色固体)、三氟化锎(亮绿色固体)和三碘化锎(柠檬黄色固体)。其它+3价的还有硫化物和环戊二烯配合物。+4价的典型化合物有二氧化锎(棕褐色固体)和四氟化锎(绿色固体)。+2价的有二溴化锎(黄色固体)和二碘化锎(暗紫色固体)。 (zh)
