What could be the metal, if a chemistry student takes a small amount of paste of metallic salt on clean platinum wire loop of the salt with concentrated $\mathrm{HCl}$ and keeps it in a non-luminous bunsen flame, the colour of the flame changes to grassy green ?

• A chloride dissolves appreciably in cold water.
• When placed on a platinum wire in Bunsen flame, no distinctive colour is noticed.

The cation which shows both of the above properties is
