Strategy:
 Analyze the successive ionization enthalpies. Removing an electron from a cation () requires significantly more energy than from a neutral atom () due to increased effective nuclear charge and smaller radius.

Step 1: Evaluate Assertion (A)
-  is always greater than  for an element.
- For Magnesium, removing a second electron means pulling it from a  cation, where the remaining electrons are held more tightly. (True)

Step 2: Evaluate Reason (R)
-  is indeed smaller and carries a high
