The decrease in atomic radii is very prominent in:
Correct answer: B. Second period
- A. Second group
- B. Second period
- C. Higher groups
- D. Higher periods
Explanation
The decrease of atomic radii is very prominent in the second period because in all elements in period 2, as the atomic number increases, the atomic radius of the elements decreases, the electronegativity increases, and the ionization energy increases.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
