What is the trend for ionization energy as you move from top to bottom down a group in the periodic table?
A. Ionization energy increases.
B. Ionization energy decreases.
C. Ionization energy remains constant.
D. Ionization energy fluctuates.
Answer:B
What is the trend for ionization energy as you move from top to bottom down a group in the periodic table?
A. Ionization energy increases. B. Ionization energy decreases. C. Ionization energy remains constant. D. Ionization energy fluctuates.
Explanation: When going from top to bottom down a group, the effective nuclear charge decreases due to increased shielding by inner electrons, making it easier to remove electrons from the outermost energy level, resulting in a decrease in ionization energy.
