Question

Consider the given statements and choose the correct option:

Statement 1: Polyatomic ions can have either positive or negative charge.

Statement 2: Ammonium ion and phosphonium ion are negatively charged ions.

• 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 A

Only statement 1 is correct
Polyatomic ions are the ions that contain more than one atom. They can be either positively charged or negatively charged. Ammonium ion $\left(N{H}_4^{+}\right)$ and phosphonium ion $\left(P{H}_4^{+}\right)$ are positively charged ions.

Hence, the correct answer is option (a).
