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 star matterIn the present paper, we study exotic phases in hot neutron–proton–electron (NPE) matter. It is shown that for densities lower than the normal nuclear matter inhomogeneous (exotic or pasta) phases may be present. This is believed to occur due to the so-called frustration...

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
A neutron breaks into a proton and electron. Calculate the energy produced in this reaction in MeV. Mass of an electron =9xx10^(-11) kg. mass of proton=1.6725
Neutron, neutral subatomic particle that, in conjunction with protons, makes up the nucleus of every atom except ordinary hydrogen (whose nucleus has one proton and no neutrons). Along with protons and electrons, it is one of the three basic particles ma
