a科学家曾一度认为没有比原子更小的东西了,但现在大多数人都知道原子是由更小的粒子构成的。 The scientist once did not think compared to an atomic smaller thing, but the present majority people all knew the atom was constitutes by a smaller granule.[translate]...
Each element is made up of atoms that are composed of even smaller particles. The difference between one element and another is because of the difference in the number of protons in their atoms. However, some atoms of the same element have different numbers of neutrons; those different atoms ...

Atoms arethe basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons. What is inside a atom?
Atoms and Atomic Structures All matter is made up of atoms. Atoms are composed of subatomic particles: Protons (+ charge) Neutrons (neutral charge) Electrons (- charge) Atoms to Elements When like atoms accumulate, they form elements. Each element is characterized by the properties inherent from...
Atoms are in turn made up of minuscule nuclei surrounded by a cloud of particles called electrons. Nuclei are composed of particles called protons and neutrons, which are themselves made up of even smaller particles called quarks. Quarks are believed to be fundamental, meaning that they cannot ...
In order to understand how heat engines worked — along with all the attendant concepts like temperature, pressure and entropy — physicists realized that they could view gases and fluids as if they were composed of a nearly numberless quantity of tiny, even microscopic, particles. For example, ...
