Explanation:
nucleus :-
A nucleus is a membrane-bound organelle that contains the cell's chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.
protons:-
The definition of a proton is a particle with a positive charge that is in the nucleus of an atom. An example of a proton is the single proton in the nucleus of a hydrogen atom. ... The proton is a basic component of all atomic nuclei and the nucleus of the protium isotope of hydrogen.
electrons:-
An electron is a stable subatomic particle with a negative electrical charge. Unlike protons and neutrons, electrons are not constructed from even smaller components. Each electron carries one unit of negative charge (1.602 x 10-19 coulomb) and has a very small mass as compared with that of a neutron or proton..

Answer:
The nucleus, protons and neutrons are the parts of an atom. the nucleus is presesnt in the centre of an atom. The nucleus consists of the positively charged protons. around the nucleus, there are imaginary orbits which contain the electrons. these orbits have names such as K shell, L shell, M shell, N shell. the number of the electrons present in the orbits of the atom is always equal to the number of protons in the nucleus.
