Question

An element ‘X’ has atomic number 11. Write the nature of the oxide of X.​

Answer 1

Answer:

Basic Oxide

Explanation:

Atomic No. 11 = Na (Sodium)

The oxide of Sodium is $Na_{2}$O

Metallic Oxides are Basic and Na is a metal

Answer 2

The nature of the oxide of X will be basic.

• The electronic configuration of the element will be 2,8,1.
• The element has one electron in its outermost shell, which indicates it belongs to group 1 of the periodic table. These elements are metallic.
• Moreover, metallic elements form basic oxides, and hence, element X will also form basic oxide.
• The formation of basic oxide is evident by the fact that in a case of reaction with water, bases containing hydroxyl ions are formed.
