Explain how changing protons, neutrons, and electrons affects atoms

Changing the number of electrons affect an atom's charge.

Changing the number of neutrons will produce an isotope of the atom.

Changing the number of protons will turn one atom into the other. For instance, Oxygen has 8 proton, if the proton number is increased by 1, the atom will become Fluorine, which has 9 protons

It put a huge effect on an atom because when atom gain or loss electon's it chagr the chemical properties of an atom.
