Answer
Completing each of the following statements a to d using 1, 2, or 3:
1. decreases 2. increases 3. remains the same
Going down Group 6A (16),
a. the ionization energy ____decreases_____
b. the atomic size ____increases_______
c. the metallic character ___increases_____
d. the number of valence electrons ____remains the same_____
Work Step by Step
when going down a group
a. the ionization energy decreases because the valence electrons are easier to remove
when they are far away from the nucleus (because of increasing atomic size).
b. the atomic size increases because of the increase in the number of energy levels.
c. the metallic character increases because the valence electrons are easier to remove
when they are far apart from the nucleus (because of increasing atomic size).
d. the number of valence electrons remains the same.
