Definitions

n.名词 noun
  1. 1

    Physics, Chemistry.

    • : a positively charged elementary particle that is a fundamental constituent of all atomic nuclei. It is the lightest and most stable baryon, having a charge equal in magnitude to that of the electron, a spin of ½, and a mass of 1.673 × 10-27 kg. Symbol: P

Examples

  • That’s some 30 times the energy of the protons that race around the world’s largest and most powerful particle accelerator, the Large Hadron Collider.

  • Perhaps the most familiar and ubiquitous of these is the proton.

  • Another is to explore how the proton's charge influences the behavior of an electron orbiting it in a hydrogen atom, which consists of only a single proton and electron.

  • In our star, the vast majority come from the direct fusing of protons.
