If you mean "What property determines which element an atom is?" then it's all about the atomic number, Z, which is the amount of protons in the atom. Atoms can vary within the element by means of loss/gain of electrons (Ionization) or by loss/gain or neutrons (Isotopes) however, ...
The atomic number (原子序数) is equal to the number of electrons per atom or, what is equivalent, the number of protons (质子) per nucleus.相关知识点: 阅读 文言文阅读 文言题类 文言文阅读——翻译 试题来源: 解析 [答案]原子序数等于每个原子的电子数或者相当于每个原子核的质子数。反馈...
Protons supply the positive charge, and each element has a different number of them. The number of protons in the nucleus determines the atomic number of an element. It's different from atomic mass or atomic weight, which take into account the presence of neutrons. Every atom of a given ...
When an atom reacts, it can gain or lose electrons, or it can share electrons with a neighboring atom to form a chemical bond. The ease with which an atom can gain, lose or share electrons determines its reactivity. Atomic Structure ...

It is the number of protons that determines the atomic number, e.g., H = 1. The number of protons in an element is constant (e.g., H=1, Ur=92) but neutron number may vary, so mass number (protons + neutrons) may vary.
On my screen, each of the atomic red dots is about 10 million times bigger than a typical atom. (Your screen may be bigger or smaller than mine, or scaled differently, so take that as a very rough approximation.)Sponsored linksContents What is an atom? What are the parts of an atom?
