Question

Iodine can form the ions ______.

विकल्प

• I⁻

• I⁺

• I³⁺

• All of these

Answer 1

Iodine can form the ions I⁻, I⁺ and I³⁺.

Explanation:

Iodine can form ions like I⁻ by gaining an electron, and under certain conditions, it can also form positive ions such as I⁺ and I³⁺ due to a slight metallic character and availability of vacant d-orbitals. Therefore, iodine can exist as I⁻, I⁺, and I³⁺ ions depending on the situation.
