Which metal ion gives a violet bead in the borax bead test?

What type of information is collected using $FTIR$ (Fourier transform infrared) spectroscopy?

$A$ chemistry student trying to detect the metallic ion in a salt,makes a paste on a clean platinum wire loop of the salt with concentrated $HCl$. When he takes a small amount of this paste and keeps it in a non-luminous Bunsen flame,the colour of the flame changes to grassy green. He should,therefore,conclude that the metal is
