The charge of two H⁺ ions is ________.

Correct option is B

The correct answer is (b) +3.2 × 10⁻¹⁹ C.
• Charge of one proton (H⁺ ion) = +1.6 × 10⁻¹⁹ C.
• Charge of two H⁺ ions = 2 × 1.6 × 10⁻¹⁹ C = 3.2 × 10⁻¹⁹ C.
Information Booster
• Elementary charge [e] = 1.6 × 10⁻¹⁹ C.
• Proton carries positive, electron carries negative charge.
Additional Knowledge
• Neutrons have no charge.
• Charge is always conserved in physical processes.
