核能,是原子核能的简称,人们习惯上又称之为原子能,其实,顾名思义,原子核能是原子核裂变产生的能量,而不是原子分裂产生的能量。五彩缤纷,变幻莫测的物质世界是由112种元素组成的,组成元素的最小单位是原子,原子由原子核和核外的电子组成,原子核又由质子和中子两种最主要的“基本粒子”构成的。如果用小孩玩的弹子球作一个参照物,原子的大小与它相比就同它与月亮相比一样。原子核则更小,要是把原子比作学校的运动场那么大,原子核的大小则只相当于放在运动场正中央的一颗仁丹药丸。 Nuclear energy is the abbreviation of atomic nuclear energy. People are customarily called atomic energy. Actually, as the name suggests, nuclear energy is the energy produced by nuclear fission, not the energy produced by atom division. The colorful and unpredictable material world is composed of 112 elements. The smallest unit of the constituent elements is the atom. The atom consists of the nucleus and electrons outside the nucleus. The nucleus consists of two main “basic particles”: proton and neutron. Constituted. If you use a pinball played by a child as a reference, the size of the atom is the same as it is when compared to the moon. The atomic nucleus is even smaller, if the atom is as large as the school’s sports field, and the size of the nucleus is only equivalent to a Rendan pill in the center of the stadium.
