Question

How did quarks fit into an atomic model?

Answer 1

Hint :A quark may be a sort of fundamental particle and a fundamental constituent of matter. Quarks combine to make composite particles called hadrons, the foremost stable of which are protons and neutrons, the components of atomic nuclei.

Complete Step By Step Answer:
Electrons occupy an area that surrounds an atom's nucleus. Each electron has an electrical charge of -1. Quarks structure protons and neutrons, which, in turn, structure an atom's nucleus. Each proton and every neutron contains three quarks. A quark may be a fast-moving point of energy. There are several sorts of quarks.
 Protons and neutrons are composed of two types: up quarks and down quarks. Each quark features a charge of +2/3. Each quark features a charge of -1/3. The sum of the fees of quarks that structure a nuclear particle determines its electrical charge.
Protons contain two up quarks and one quark. +2/3 +2/3 -1/3 = +1 Neutrons contain one quark and two down quarks. +2/3 -1/3 -1/3 = 0.
The nucleus is held together by the "strong nuclear force," which is one among four fundamental forces (gravity and electromagnetism are two others). The strong interaction counteracts the tendency of the positively-charged protons to repel one another. It also holds together the quarks that structure the protons and neutrons.

Note :
Additionally to electrons and quarks, physicists have identified a variety of other subatomic particles. In physics it describes the subatomic world together that can't be depicted in diagrams - particles aren't dots in space (as depicted during this feature), but are more like "dancing points of energy.
