Slide 1: 

Test for metal ions (source below)

  1. Dip nichrome wire in HCl.
  2. Dip wire in solid.
  3. Heat wire in centre of flame.
  4. Observe colour of flame.

Slide 2:  If the question ask why different colors are produced (fact check this) it is due to the shells being different distances apart.
