Abstract IT has recently been suggested by Bondi and Ly ttleton1,2that 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 fact, Piccard and Kessler3...
Comparison of the Charges of the Electron, Proton and NeutronWE have noted the communication from Bondi and Lyttletoncriticizing our experimentand we would like to clarify the alleged obscurities.A. M. HILLAST. E. CRANSHAWNature
The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom....

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
Atom (原子)被认为是the smallest part of an element that has the properties of that element,它自身又由proton (质子), neutron (中子)和electron (电子)组成。虽然electron的质量仅为proton or neutron的1/1836,但它在许多方面(e.g. ionisation...

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...
element determines its atomic number, Z. Hydrogen is the lightest element and has one proton (Z = 1); uranium is the heaviest naturally occurring element and has 92 protons (Z = 92). Each proton, which is assigned a mass of 1.00728 atomic mass units (amu), has a charge designated as...
