Question

Diagonal similarities are due to the similar polarising power of elements. Polarising power is directly proportional to:

• A. $\frac{charge}{radius}$
• B. $\frac{charge}{(radius{)}^2}$
• C. $\frac{(charge{)}^2}{radius}$
• D. $\frac{charge}{(radius{)}^{1/2}}$

Answer 1

Answer: (A)

$\frac{charge}{radius}$

$Polarisingpower\alpha \frac{charge}{radius}$

Because of polarising power, diagonal similaritis are there.

These diagonal similarities are mostly present between period $II$ and period $III$ elements as they have less radius.
