Polyatomic ions describes ions which are posses more than one atom. Hence, the formula which represents a polyatomic atomic ion is 
- Sulphates contain both Sulphur and Oxygen atoms, hence, they contain two atoms, thus they are polyatomic.
- Sulphide are represented as
; containing only Sulphur atom, hence, they are mono atomic.
- Chlorides are represented as
; containing only chlorine atoms, hence, they are mono atomic.
- Nitrides are represented as
; containing only Nitrogen atom, hence, they are also mono atomic.
Therefore, sulphates are polyatomic as they contain more than one atom.

There are different kinds of experiment. The relationship between volume and temperature is that As temperature goes up, volume also goes up when pressure is held constant.
- As seen in the data, as the temperature often increases the volume in each gas therefore still increases slightly.
<h3>What is the relationship between volume and temperature?</h3>
Note that the volume of any gas or substance is said to directly proportional to its temperature.
Charles's law gave the theory that the volume of a given amount of gas is certainly proportional to its temperature using the kelvin scale when the pressure is known to be constant.
