Question

Please help!!!! ⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️

Answer 1

Polyatomic ions: $CH_3COO^-$, $NO_3^-$, $NH^+$, $CN^-$, $Li^+$, and $OH^-$

Monatomic ions: $Ca^{2+$, $O^{2-$, and $Fe^{3+$

Monoatomic vs Polyatomic Ions

In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include  $Ca^{2+$, $O^{2-$, and $Fe^{3+$

Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.

Examples of polyatomic ions are  $CH_3COO^-$, $NO_3^-$, $NH^+$, $CN^-$, $Li^+$, and $OH^-$

Thus, from the diagram:

• Polyatomic ions: $CH_3COO^-$, $NO_3^-$, $NH^+$, $CN^-$, $Li^+$, and $OH^-$

• Monatomic ions: $Ca^{2+$, $O^{2-$, and $Fe^{3+$
