Question 21

Particles of matter that make up protons and neutrons are ____.


A)electrons

B)isotopes

C)quarks

D)atoms

Answer 1

Quarks are the particles of matter that make up protons and neutrons, and they were discovered through experiments involving high-energy electron scattering off protons.

Step-by-step explanation:

The particles of matter that make up protons and neutrons are called quarks. Protons and neutrons, collectively known as nucleons, are the two types of particles that reside in an atom's nucleus and account for nearly all of its mass. During experiments that involved scattering high-energy electrons off of protons, researchers observed behavior that provided nearly direct evidence of quarks. This scattering sometimes resulted in electrons deflecting straight backward, suggesting the presence of very small, dense particles making up the proton. The discovery of quarks was a landmark in understanding the fundamental structure of matter.

Answer 2

The particle is C) Quarks.

Step-by-step explanation:

A quark is a kind of basic molecule and a crucial component of matter. It combines to frame composite particles called hadrons, which are nothing but protons and neutrons, which are considered as sub-atomic particle of the atom.

Because of a wonder known as shading repression, quarks are never straightforwardly watched or found in detachment; they can be discovered distinctly inside hadrons, which incorporate baryons, (for example, protons and neutrons) and mesons. Thus, a lot of what is thought about quarks has been drawn from perceptions of hadrons.
