Protons and Neutrons: What Are They?Jean Louis Van Belle
Atoms are made from a nucleus of protons and neutrons and a cloud of electrons.A. 正确B
How are protons and neutrons different from and similar to each other? Discovery of Subatomic Particles: Until 1897, scientists believed that there was no smaller unit of matter in existence than the atom. This changed when J.J. Thomson first discovered the electron, proving the existence o...
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 ...
Why neutrons and protons are modified inside nuclei 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 pheno... G Feldman - 《Nature》
and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge. In accordance with theStandard Model of particle physics, protons and neutrons make up the nucleus of the atom, while ...
