1.What is a proton, neutron, and electron?什么是质子,中子和电子?The proton is a subatomic particle with an electric charge of +1 elementary charge.The neutron is a subatomic particle with no net electric charge and a mass slightly larger than that of a proton.Proton and neutron are usually...
例如“proton质子”,取自希腊语“πρῶττις”,意思是“第一”,因为它们被认为是重物质的主要成分(质子比电子重1836倍)。这个词的词尾与“electron”中的词尾完全相同。 在20世纪30年代,一种与质子质量大致相同的中性粒子被发现并被认为也是普通物质的基本组成部分,它被命名为“中子neutron”,以拉丁语单词...

neutron是中子，proton是质子，electron是电子。中子不带电，质子带正电，电子带负电。中子与质子通过强相互作用结合，形成原子核，电子在核外运动
We study the evolution of the \\eep cross section on nuclei with increasing\nasymmetry between the number of neutrons and protons. The calculations are done\nwithin the framework of the nonrelativistic and relativistic distorted-wave\nimpulse approximation. In the nonrelativistic model phenomenological\...

is positive. The equal positive charge of the proton and the negative charge of the electron cancel each other. Therefore, the atom has no net charge. In a neutral atom, the number of electrons revolving around the nucleus and the number of protons inside the nucleus are equal in number....
THE neutron is usually looked upon as an aggregate of a proton and an electron. If it were so, there ought to be a strong tendency for hydrogen atoms to be converted spontaneously into neutrons, and the number of neutrons present in the universe should be much higher than it is assumed ...
