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...
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
‘e’ represents an electron and it contributes to the negative charge of an atom. The absolute charge of an electron is the negative charge of 1.6×10-19coulombs. The relative mass of an electron is 1/1836. Furthermore, the mass of an electron is 0. Discovery of Proton Proton was dis...

In a paper written early in 1919, the formula of the beryllium nucleus was given as α(ηβ) which in more recent symbols is α(pe), where the parentheses were used to emphasise the idea that the proton p and the electron e are united to form a neutral group or neutron....
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
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
Question. A proton, a neutron, an electron and an a particle have same energy. Then their de- Broglie wavelengths compare as? 相关知识点: 试题来源: 解析 Answer. m_p=m_n>m_e, \lambda_e\lambda_\alpha%" font-base="12" src="http://gallery.fbcontent.cn/latex?decode=false&latex=%24...
