核能．是原子核结构发生变化时放出的能量．也叫原子核能或原子能；它将是21世纪主要的能源之一，占有十分重要的地位．一、原子核的组成原子核是由质子和中子两种微粒组成的．每个质子带1个单位的正电荷，中子不带电．核内的质子数，就是原子核所带的正电荷数，即核电荷数．在
nuclear energy. It is the energy released when the nuclear structure changes. It is also called atomic nuclear energy or atomic energy; it will be one of the major energy sources in the 21st century and occupies a very important position. 1. Atomic nucleus The nucleus is composed of two kinds of particles: proton and neutron. Each unit has a positive charge of 1 unit and neutrons are not charged. The number of protons in the nucleus is the number of positive charges carried by the nucleus, that is, the number of nuclear charges. in
