Question

proton n.质子 (1) 质子和中子构成电荷双重态。(2) 三硝基甲烷是一个极强的质子给予体。 The atomic number of an element, which is the number in the upper left corner of its box on the periodic table, is the number of protons in each atom. The hydrogen atom, for example, has just one proton, so it also has one electron and its atomic number is 1. If you have an atom with two protons in its nucleus, you know it can't be a hydrogen atom.

Accepted Answer

英 ['prəʊtɒn] 美 ['proʊtɑːn] (1) Proton and neutron form a charge doublet.(2) Nitroform is such a strong proton donor. Atoms are made up of three main particles: protons, electrons, and neutrons. A proton has a positive electrical charge, while electrons are negative. The number of protons and electrons is equal in each atom. 1[N-COUNT 可数名词]质子 A proton is an atomic particle that has a positive electrical charge.   [TECHNICAL 术语]
