Cl2 is also known as chlorine gas. iv. Cl2 form exists in nature. The atomic mass of this element is (Atomic mass of chlorines × 2) = 35.5 × 2 = 71u

Answer 2

Explanation:

This is quite a common confusion between students learning elements for the first time, I will try my best to clear it!

When you say Cl, it refers to the element Chlorine.  While $Cl_{2}$ refers to one molecule of Chlorine with two atoms. Similarly, $4Cl_{2$ simply refers to 4 molecules of a diatomic chlorine molecule. Since you're only in 9th grade right now, you don't need to worry too much about this. In the first chapter of 10th grade, you'll learn all about it.

I hope this helps!!
