Nuclear physics and basic technology 1.4.1 Unstable nuclei Figure 1.2 gives the combinations of protons and neutrons that are found to be stable nuclei. This information may also be presented as an area of stability, Fig 1.4. Nuclei lying outside this area may be regarded as having the wrong...
: the central part of an atom that includes nearly all of the atomic mass and consists of protons and usually neutrons Etymology from modern Latin nucleus "the central part of something," from Latin nucleus "kernel," derived from nux "nut" Medical Definition nucleus noun nu·cle·...
· Empty space - whereas the atomic nucleus has an empty space between the nucleus and the electron cloud, the cellular nucleus does not have any empty space (this is due to the presence of nucleoplasm)· Nucleus components - Whereas the atomic nucleus consists of protons and neutrons, the ...
At the centre of every atom is the atomic nucleus. The nucleus consists of particles calledprotonsand neutrons(collectively callednucleons) and contains almost all of the atom's mass, but is extremely tiny, with a diameter of about 10^-15 metres (0.000 000 000 000 001 m) or one femtomet...

Atoms are made from a nucleus of protons and neutrons and a cloud of electrons.A. 正确B
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
The symbol for each atom is identified. Concept Introduction: Mass number : The sum of protons and neutrons gives the value of atomic mass . A (mass number) = no .of protons (P) + no .of neutrons (N) The element symbol : Z A X where, A (a...
