frpm.elements can be classified by there state (or phase )at room temperature.the state means whether the element is a solid.liquid or gas.substances which contain different elements are either mixtures or compounds.最好不要用翻译器.(现在我馍有财富值了.赚够多少一定全部抛出感谢)话是这样讲 可...
解析 首先句子后面是作定语的,由主句可以知道,修饰的是主语element.因为atoms是原子的意思,对于元素来说,逻辑关系自然是“元素里的原子”,所以element和atoms具有从属关系,用whose(注意啦!在定语从句表示从属关系的时候,关系词whose不仅仅适用于人,也可以适用于物)...
If you know where a certain element sits in the table, and you know a little bit about the properties of the elements above, below, and either side, you can often figure out what the properties of that element will be.How do atoms make molecules and compounds? Atoms are a bit like ...
