根据第一段中remember that the periodic table is used to organize all the elements, or things that make up(组成)our world.可知是组成我们的世界的东西,故选B。 根据第二段开头Elements are all around us.可知元素遍布我们周围,后面列举了一些常见的元素,故选A。 根据文中Last December, scientists from...
The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom in order of increasing atomic number, or the number of protons in anatom's nucleus, which ge...
