Ionization is the removal of an electron from an atom by supplied energy. Which option best represents this definition?

Ionization is about removing an electron from an atom with energy input, creating a positively charged ion and a free electron. The statement that ionization involves the removal of an electron by supplied energy directly matches this process, which is why it’s the best representation. Adding electrons would form a negatively charged species, forming a positive nucleus refers to changes in the nucleus itself, and changing a solid to a liquid is a phase change, not ionization. Ionization energy is the threshold needed to overcome the electrostatic hold of the nucleus on the electrons, a concept fundamental to how X-rays interact with matter.
