Questions and Answers

What is the definition of ionization energy?

  • The energy required to break an atom into smaller subatomic particles.
  • The maximum amount of energy required to add an electron to an atom.
  • The energy released when an electron is added to an atom.
  • The minimum amount of energy required to remove the outermost electron from an atom. (correct)
  • Why are valence electrons the first to be stripped away during ionization?

  • Because they are closest to the nucleus.
  • Because they are the furthest from the nucleus and influenced the least by it. (correct)
  • Because they have a stronger negative charge.
  • Because they have the highest energy level.
  • How does ionization energy change as more electrons are removed from an atom?

  • It decreases due to reduced electron-electron repulsion.
  • It remains constant regardless of the number of electrons removed.
  • It fluctuates depending on the electron's energy levels.
  • It increases because it becomes harder to remove electrons. (correct)

    Why does an ion with a positive charge have a tighter hold on its remaining electrons?

    <p>Because it has lost electrons and now has a greater positive charge.</p> Signup and view all the answers

    What happens to an atom's ionization energy as its positively charged influence on electrons increases?
