On December 1st 2011, the IUPAC announced theproposed names for elements 114 and 116. Element 114 would be named flerovium with the symbol Fl, while element 116 would be named livermorium with the symbol Lv. There will be a five month comment period for the new names. If all goes well ...
周期表上,一个元素的基本信息一般都会被标注在元素的符号(symbol / chemical symbol)周围。 化学里的元素(element)基本可以分成 metal(金属) 与 nonmetal (非金属) 两类,金属元素又有一系列特别的 transition metals(过渡金属)。周期表上金属与非金属交界处又有着一系列具有特殊性质的元素,被称为 metalloid(准金属...
