Question

The alloy formed by lithium with metal 'X' is used to make armour plates. 'X' is

• A. Mg
• B. Pb
• C. Al
• D. Sn

Hint:

Magnesium-lithium alloys are lightweight and have high strength, making them suitable for use in armour plates and aerospace applications.

Answer 1

The Correct Option is A

- The alloy formed by lithium with magnesium (Mg) is called magnesium-lithium alloy, which is used in the making of armour plates. Hence, option (1) is correct.
- Lead (Pb), Aluminum (Al), and Tin (Sn) are not used in the formation of such alloys for armour plates. Therefore, options (2), (3), and (4) are incorrect.
