Question

A basic oxide will be formed by the element ______.

पर्याय

• K

• S

• P

• Kr

Answer 1

A basic oxide will be formed by the element K.

Explanation:

Potassium (K) is an alkali metal, and metals characteristically react with oxygen to form basic oxides. When potassium oxide (K₂O) dissolves in water, it produces a strong base called potassium hydroxide (KOH). Conversely, Sulphur (S) and Phosphorus (P) are non-metals that form acidic oxides, while krypton (Kr) is an unreactive noble gas.
