21. When an atom loses an electron to become an ion, what happens to its electric charge? To
its size? Write a chemical equation that shows the process or events in the formation of this ion.
What energy value is associated with this process?
When an atom loses an e- to become an ion, the atom becomes a cation and has a positive
charge. The energy value associated with this process is called ionization energy, the amount of
energy required to remove an e- form a neutral atom.
A – e-
A+
