解析 就是单数复数啦... 比如说proton就是一个质子,protons就是多个质子……氢就是one proton…… 在这几个词中,nucleus比较特殊.nucleus是单数,nuclei是复数【参见半径单数=radius复数=radii】 分析总结。 比如说proton就是一个质子protons就是多个质子
BEIJING, Feb. 22 (Xinhua) -- Chinese researchers have synthesized two new nucleus isotopes that contain 84 neutrons and 82 neutrons, according to a recent research article published in the journal Physical Review Letters. The nucleus is composed of protons and neutrons. Different numbers of protons...
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 ...
Physicists often state that nuclear shell structure - the way in which protons and neutrons are arranged within a nucleus - is the cornerstone of any satisfactory description of an atomic nucleus. But over the past decade it has become apparent that the ...

5. Physics The positively charged central region of an atom, composed of protons and neutrons, about which negatively charged electrons orbit. Extremely small and dense, the nucleus contains almost all of the mass of an atom. 6. Chemistry A group of atoms bound in a structure, such as a ...
This means that nucleons (protons and neutrons) are interacting with an attractive force called the nuclear force with an action range of about 1 fm (femtometer or fermi) except the inter-nucleon distance |R| is not too small (|r|≥ 0.1 fm). Let us consider an interaction of two nucle...
