The number of protons can not be changed.
The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.
Atoms consist of a nucleus and electrons surrounding the nucleus. You can not change the nucleus by ordinary chemical means but you can remove electrons. However, since the electrons are easily replaced the atom is not considered fundamentally changed by removing electrons, but it is changed. There is a way to change a nucleus that's called "neutron activation" . This involves bombarding the nucleus with slow moving neutrons and letting the nucleus adsorb a neutron. This makes the atom a little heavier and can sometimes make the atom radioactive. Neutron activation is not considered a chemical process but it is a way to change the atom. So I would say it is incorrect to say an atom cannot be changed. Atoms can be changed but its not easy.
An atom is a unit of matter that cannot be split into other atoms. It is made of energy.
The nucleus of an atom CANNOT itself contain atoms.
the growth of the atom slows down and when the process of change happends the atom will multiply

atoms cannot be divided
I cannot answer this question.
Sometimes, an atom cannot be split.

All of the elements of the Periodic Table cannot be broken down into simpler substances.
Nuclear change is the change in the nucleus of the atom.

how will the electron configuration of the atom change when the atom becomes an iron
