Questions & Step-by-Step Solutions

What is the ionization energy of an atom? (2023)
  • Step 1: Understand that an atom is made up of protons, neutrons, and electrons.
  • Step 2: Know that electrons are negatively charged particles that orbit around the nucleus of the atom.
  • Step 3: Realize that ionization energy is about removing one of these electrons.
  • Step 4: Remember that ionization energy is the amount of energy needed to take an electron away from the atom.
  • Step 5: Note that this process happens when the atom is in a gaseous state, meaning it is not part of a solid or liquid.
