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 stab
· 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...
The interaction in the nucleus of protons and neutronsTysinyuk Nikolai Maksimovich
1 :a usually round part of most cells that is enclosed in a double membrane, controls the activities of the cell, and contains the chromosomes. 2 : the central part of an atom that comprises nearly all of the atomic mass and that consists of protons and neutrons. ...
(原子)核 the central part of an atom, consisting of protons and neutrons · C 2. 中心,核心 central part, around which other parts are grouped or collected · 句型例句 The nucleus of an atom consists of neutrons, protons and other particles.原子核 由中子、质子和其他粒子构成。 Many people ...
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
Atoms are made from a nucleus of protons and neutrons and a cloud of electrons.A. 正确B
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...
