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
electronprotonneutronuniversality of gravitational interactionFrom the viewpoint of general relativity theory (GRT), the obstacles are discussed that do not allow gravitational and electromagnetic fields to be used to create a model of elementary particles and atomic nuclei, including vanishingly small ...
A neutron has mass number 11. An electron has mass number 00. With this definition you consistently get the mass number of an atom/ion by summing the mass numbers of its constituents. For example: the Na atom and the Na++ ion both have mass number 2323. Don't confuse these mass num...

IT has recently been suggested by Bondi and Ly ttleton1,2 that the magnitudes of the electric charges on the proton and electron may differ by a little more than one part in 1018, in which case electrostatic forces would cause the universe to expand. In
Human manganese superoxide dismutase is a critical oxidoreductase found in the mitochondrial matrix. Concerted proton and electron transfers are used by the enzyme to rid the mitochondria of O2•−. The mechanisms of concerted transfer enzymes are ty
