Can you say that atoms cannot be changed?

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.
