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...
459, the relation between the satellites of mercury lines and the isotopes, we have found that the structure of the line 3131.84 does not satisfy the relation given by the formula therein used. The differences in wave-lengths are all too small. To explain this anomaly, we assume that in ...
Atom - Electrons, Nucleus, Bonds: Once the way atoms are put together is understood, the question of how they interact with each other can be addressed—in particular, how they form bonds to create molecules and macroscopic materials. There are three bas
An electron orbiting a nucleus is electrically attracted to the nucleus; it's always being pulled closer. But the electron also has kinetic energy, which works to send the electron flying away. For a stable atom, these two are in balance. In fact, the total energy of an electron in ...
Atoms are composed of 3 subatomic particles; protons, neutrons, and electrons. Protons are positively charged species, neutrons are neutral species, and electrons are negatively charged species. The protons and neutrons of an atom form the nucleus. The electrons are located outside ...
