质子是什么——质子的特性

A proton symbol p or p is one of the subatomic particles that make up matter. In the universe protons are abundant making up about half of all visible matter. It has a positive electric charge ( 1e) and a rest mass equal to 1.67262 × 10−27 kg (938.272 MeV/c2)— marginally lighter than that of the neutron but nearly 1836 times greater than that of the electron. The proton has a mean square radius of about 0.87 × 10−15 m or 0.87 fm and it is a spin – ½ fermion.

质子，符号为p或p ，是构成物质的亚原子粒子之一。在宇宙中，质子非常丰富，约占所有可见物质的一半。它带正电荷( 1e)，静止质量等于1.67262 × 10^−27 kg (938.272 MeV/c^2)，比中子略轻，但比电子重近1836倍。质子的均方半径约为0.87 × 10^−15 m或0.87 fm，是一个自旋½的费米子。

The protons exist in the nuclei of typical atoms along with their neutral counterparts the neutrons. Neutrons and protons commonly called nucleons are bound together in the atomic nucleus where they account for 99.9 percent of the atom’s mass. Research in high-energy particle physics in the 20th century revealed that neither the neutron nor the proton is not the smallest building block of matter.

质子存在于典型原子的原子核中，伴随着它们的中性对应物中子。中子和质子，通常被称为核子，在原子核中结合在一起，它们占原子质量的99.9%。20世纪高能粒子物理学的研究表明，中子和质子都不是物质的最小组成部分。
