Question

Statement 1 (S1): Ammonium ion carries +1 charge.​
Statement 2 (S2): A group of atoms carrying a positive charge is known as a polyatomic cation.​

• A. S1 is false but S2 is true ​
• B. S1 is true but S2 is false​
• C. Both S1 and S2 are false​
• D. Both S1 and S2 are true​

Answer 1

The correct option is D Both S1 and S2 are true​

An ammonium ion is represented by ${{\mathrm{NH}}_4}^{+}$
It has a +1 charge on it.

Hence, S1 is true.

A polyatomic cation is a group of atoms carrying a positive charge on them.
Example- ${{\mathrm{NH}}_4}^{+}$

Hence, S2 is true.
