Q. Illustrate what are the three particles that make up an atom?
Answer:-
Atoms are conjured of neutrons, protons, and electrons. The protons as well as neutrons are found together in the core of the atom called the nucleus which is in the centre.
The electrons are found travelling around the nucleus at different energy levels in what is called the electron cloud.
Note that in hydrogen the majority all of it is made up of just a lone proton and an electron. There are no neutrons in the majority common isotope of hydrogen (1H). Protons as well as neutrons which are called nucleons when they're found in an atomic nucleus are further made of still smaller subatomic particles called quarks.
