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 Kessler3attempted ...
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
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

求语法题a proton has a positive charge and an electron a negative charge,but a neutron has a neither b both WHY? 答案 质子带正电,电子带负电,中子不带电(正负电都不带).Neither就是都不的意思,所以选A相关推荐 1求语法题a proton has a positive charge and an electron a negative charge,but ...
The lightest stable subatomic particle known, the electron carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton. An elect...
Proton A proton is a subatomic particle, symbol p or p+, with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particl...
