Question

Assertion (A): Hydrogen is a non-metal and can even form positive ions.

Reason (R): Metals are defined as the elements which form positive ions by the loss of electrons.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true but R is not the correct explanation of A.

Explanation:

Hydrogen is indeed a non-metal that can form a positive ion ($$\mathrm{H}^+$$). The reason gives the general definition of metals, but it does not explain hydrogen's exceptional behaviour; therefore both statements are true but R is not the correct explanation.
