Ask a junior high school chemistry question

Is the atom becoming an ion a chemical change or a physical change?

I searched it and it basically said it was a chemical change. But the definition of atom is:the smallest particle of chemical change, atom cannot be divided in chemical reaction. So for example, sodium atom becomes sodium ion, and one Extranuclear electrons, if it is a chemical change, wouldn’t the structure of the sodium atom change? Sodium atoms”divide” out an electron!
