QUESTION:
The atomic and ionic radii of the first three group 6A elements are
(a) Explain why the atomic radius increases in moving downward in the group. (b) Explain why the ionic radii are larger than the atomic radii. (c) Which of the three anions would you expect to be the strongest base in water? Explain. [Sections 22.5 and 22.6]
ANSWER:Step 1 of 4
Atomic radii increase in moving downward in the group because the number of electron subshells and orbital densities in moving downward increases and nuclear charge decreases.
