Question 1 of 10
Ionization energy increases down a group because the number of protons increases and it's
more difficult to lose electrons because they are being pulled closer.

Question 5 of 10
What is the definition of ionization energy?
The energy required to add an electron
The energy required to remove an electron
The amount of energy to attract or bond an electron
None of the above are correct
Question 6 of 10
Which of the following best explains why ionization energy decreases down a group?
None of the above.
Ionization energy decreases because electrons are closer and require more energy to remove.
Ionization energy increases, because electrons are closer to the nucleus.
Ionization energy decreases because electrons are further away and require less energy to
remove.
