2Atoms, the basic building blocks of matter, are made of three basic components: protons, neutrons and electrons. The protons and neutrons cluster together to form the nucleus, the central part of the atom, and the electrons orbit about the nucleus. Protons and electrons both carry an electric...
In the science lecture, the speaker said that atoms are the basic building blocks of matter. What is an atom made up of? A. Protons, neutrons and electrons. B. Water and air. C. Sunlight and heat. D. Rocks and minerals. 相关知识点: 试题来源: 解析 A。原子由质子、中子和电子组成...
Quarks are one of the basic building blocks of matter, making up the protons and neutrons that are found in the nuclei of atoms. But a new model suggests that these subatomic particles may not be so fundamental after all, but instead just a quantum illusion. ...
Atomic Structure Matter has mass and takes up space. Atoms are basic building blocks of matter, and cannot be chemically subdivided by ordinary means. Both the protons and neutrons reside in the nucleus. Protons have a positive (+) charge, neutrons have no charge --they are neutral. ...

At the basic level, atoms are the building blocks of matter—they are what make up everything in the physical world. Atoms consist of a nucleus, which is made up of protons and neutrons, surrounded by electrons in shells. The characteristics of an atom are determined by the number of prot...
