What is the definition of ionization energy?
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?
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?
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)
