atomsHow atoms can be seen. See all videos for this article atomic number, the number of achemical elementin the periodic system and on theperiodic tablethat equals the number of protons in the nucleus of the atom. The elements are arranged on the table in order of increasing number of pr...
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)...
Find the Number of Protons Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton ...
