中英元素周期表的元素信息标注举例,截取自上文两张元素周期表 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...
In this section, we will explore the periodic table, which organizes chemical elements and provides valuable information about their properties and relationships. Understanding the periodic table is essential for studying chemistry and the elemen...
