Question

Ammonium (NH4+), carbonate (CO32−), and phosphate (PO43−) are all examples of: (a) multivalent metals (b) polyatomic ions (c) covalent molecules (d) molecular compounds. Help pleasee

Answer 1

Option b) polyatomic ions

Step-by-step explanation:

Polyatomic ions are ions consisting of two or more atoms.

From the question given above, we can see that each ions consist of more than one atom as shown below:

Ions >>>>>> Number of atom present

NH4+ >>>>> 2

CO32− >>>> 2

PO43− >>>> 2

Thus, we can say that the above ions are polyatomic ions.
