उत्तर
Potassium
Explanation:
Potassium (K) has the largest atomic radius compared to sodium (Na), magnesium (Mg), and aluminium (Al), which belong to periods 3 and 4 respectively. Potassium has the largest atomic radius among the elements, which means that atomic size increases with decreasing group.
