proton
Prononciation : [ˈproʊtɒn]
Mot
Contexte : « science »
(noun) a small particle that is found in the center of an atom. Protons are positively charged, which means they have a type of energy that attracts negatively charged particles called electrons. Protons help to determine what kind of element something is, like if it's gold or oxygen.
Exemple
An atom of hydrogen has one proton in its nucleus.
Exemple
A neutron does not have a charge like a proton does; instead, it is neutral.
Exemple
How many protons does an oxygen atom have?
Contexte : « physics »
(noun) a type of particle used in certain types of research and experiments, especially in physics. Scientists study protons to learn more about energy and matter because they play a big role in how atoms behave.
Exemple
Researchers used protons in their experiments to discover new particles.
Exemple
They did not measure neutrons in the same way that they measured protons.
Exemple
Why do scientists accelerate protons in particle physics experiments?
