Ions made up of more than one atom are called polyatomic ions.
Think about the question and each of the answers, particularly d) Polyatomic atoms. Even if I had no knowledge of chemistry, (d) would be the obvious answer. The question wants ions with MORE THAN ONE ATOM. Poly=Many/multiple, so 'polyatomic' quite literally means 'more than one atom'.
Polyatomic ions.
Ions, or more specifically Cations. When an atom loses an electron it becomes positively charged and is attracted to a cathode, hence the name cation.
When electrons move from one atom to another, they change the charge of the atoms. If you remove one electron that atom becomes 1+ charged because a negative was taken away, making it more positive than negative. The atom that recieves an electron becomes 1- charged because you added a negative, making the atom more negative than positive.
It's hard to say without seeing the context, but it probably means the ionic charge of the atoms, which is affected by the number of protons and electrons. In a regular atom these numbers are the same, bu n a positive ion, there are more protons, and in negative ions, there are more electrons.
"Polyatomic ions", like carbonate (CO32-) and ammonium (NH4+)

Polyatomic ions.
Polyatomic ions. SO4 2- = sulfate OH - = hydroxide CO3 2- = carbonate NO3 - = nitrate NH4 + = ammonium For several common examples.

Ions are made for clothes can not be wrinkly An ion is formed when an atom [or molecule] gains or loses one or more electrons. If an atom or molecule gains an electron it acquires negative charge. If the atom or molecule loses an electron it becomes positively charged.
Polyatomic ions.
no it only has one atom, but a polyatomic ions have more than one.
ions like sulphate ions,carbonate ions etc...are the ions which contain more than one atom.
Polyatomic ions are charged substances that contain more than one atom. These ions are formed when a group of atoms gain or lose electrons to achieve a stable electronic configuration. Examples include sulfate (SO4^2-) and ammonium (NH4^+).
No. A monatomic ions consists of just one atom.A polyatomic ion is made up of more than one.hint:mono=1poly= more than one.
No They are ions made up of more than one atom and acts as a single unit.
