金属英文字母贴

您好！根据国家贵重金属标准和国际铂金协会PGI解释：铂金=白金=Pt买铂金（白金）一定要认准Pt标志。容易混淆的k金不含铂金！k金/白色K金（white gold),它的主要成分是黄金，它不是天然白色的，由于加入其他金属后而呈现出白色。白色K金首饰通常使用18K或750来表示其中所含黄金的纯度。钯金，符号pd关于白金的权威定义网上有很多人不动脑子复制明显错误的答案（比如说白金是k金、是混合物等等），所以建议可以自己看百科或者网上找找“国家首饰质量监督检验中心”看看国检是怎么定义白金的。希望能帮助到您。

metal是一个最常用的金属的英文单词.没有复数形式的名词.

英文缩写?是元素符号吧...钾K钙Ca钠Na镁Mg铝Al锌Zn铁Fe铜Cu汞Hg银Ag铂Pt金Au锰Mn钡Ba这些就是比较常见的金属元素

1、银为贵金属之一，符号Ag，英文为silver。2、黄金（Gold）是化学元素金（化学元素符号Au）的单质形式，是一种软的，金黄色的，抗腐蚀的贵金属。3、铂金（Platinum，简称Pt），是一种天然形成的白色贵重金属。铂金早在公元前700年就在人类文明史上闪出耀眼的光芒，在人类使用铂金的2000多年历史中，它一直被认为是最高贵的金属之一。4、钯金，铂族的一员，元素符号Pd，外观与铂金相似，呈银白色金属光泽，色泽鲜明。5、K金的“K”是外来语“Karat”一词的编写，完整的表示法是这样的:Karat gold（即K黄金），“AU”或“G”是国际上用来表示黄金纯度（即含金量）的符号。
