Question

Consider the following statements:
Statement-1: The smallest and the lightest positive ion is obtained from hydrogen.
Statement-2: Anode rays are also known as canal rays.
Now, choose the correct option.

• A. Only statement-1 is correct
• B. Only statement-2 is correct
• C. Both the statements are correct
• D. Both the statements are incorrect

Answer 1

The correct option is C Both the statements are correct

Hydrogen is the smallest and the lightest atom. Therefore, the smallest and the lightest positive ion is obtained from hydrogen and is called proton. It is represented as $H^{+}$.
Canal rays (or anode rays) are the positively charged radiations which starts from the positively charged electrode (anode) and move towards the negative electrode (cathode) in a discharge tube when high voltage electricity is passed through a gas at a very low pressure.
Hence, the correct answer is option (c).
