Question

A polyatomic ion can be found in which of the following choices?

a. Sr+2
b. CH3COOH
c. LiBr
d. O3
e. ClO-3

Answer 1

Indeed, most ionic compounds contain polyatomic ions. Well-known examples are sodium hydroxide (NaOH) with OH- as the polyatomic anion, calcium carbonate (CaCO3), and ammonium nitrate (NH4NO3), which contains two polyatomic ions: NH+ and NO3-.

Answer 2

The Answer is e. ClO₅⁻

Step-by-step explanation:

a. Sr⁺² is mono ionic with positif charge

b. CH₃COOH is a neutral molecule, not an ion

c. LiBr is a neutral molecule, not an ion

d. O₃ is a neutral molecule, not an ion

e. ClO₃⁻ is a polyatomic ion

* Polyatomic ion is ion that performed from more that one atom
