英文词汇:molecules,nucleus,protons,neutrons,electrons一定要加S么,为什么.还是一般情况?atom呢? 答案 就是单数复数啦...比如说proton就是一个质子,protons就是多个质子……氢就是one proton……在这几个词中,nucleus比较特殊.nucleus是单数,nuclei是复数【参见半径单数=radius复数=radii】相关推荐 1英文词汇:molecule...

Atomic structure Grams are not used to measure mass of atoms because atoms are too small –Amu is used instead –Amu = atomic mass unit Amu – 1/12 th the mass of a carbon-12 atom, which contains 6 protons and 6 neutrons Isotopes Isotopes are atoms that have the same number of proton...
