In fact in a nucleus, protons and neutrons are exchanging a meson at extremely fast speeds, when the neutrons lose a meson becomes a Proton, when the Proton is a meson becomes a neutron. There is no doubt that being swapped is of positive charge. Due to due to the exchange of Mesons ...
An atom contains protons, neutrons, andelectrons. The nucleus of an atom consists of bound protons and neutrons (nucleons). The negatively charged electrons are attracted to the positively charged protons and fall around the nucleus, much like a satellite is attracted to the gravity of the Earth...
The structure of a neutron or a proton is modified when the particle is bound in an atomic nucleus. Experimental data suggest an explanation for this phenomenon that could have broad implications for nuclear physics. A modification of the structure of nucleons in correlated pairs....

The number of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom is determined very nearly by the total number of protons and neutrons in its nucleus. This total is called the mass number, A. The number of neutrons in an atom, ...
The meaning of PROTON is an elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electro
Protons and neutrons are held together at the center of an atom by powerful nuclear forces. A theory that can describe the interaction between just two of these subatomic particles could potentially be extended to predict the existence and properties of
Protons and neutrons(together called nucleons)are held together in the nucleus of an atom by a force called the strong force. At very small separations, the strong force between two nucleons is larger than the repulsive electrical force between tw...
a也就是说铁元素原子核中的中子与质子要比其它所有元素原子核中的中子与质子靠近得更紧密,其中子与质子间的强相互作用力也最大,因而当其向同一个方向排列时,其也具有最大的磁场。 In other words, in the hard element atomic nucleus neutron and the proton must approach compared to other all element atomi...
A test of the interacting boson-fermion model in a single j-shell of neutrons and protons An isospin invariant form of the interacting boson-fermion model is shown to reproduce realistic shell-model results for odd nuclei in a single j= 7 2 shel... JA Evans,PV Isacker,JP Elliott - 《...
