Explanation / Answer

Question 1.

Li,Lithium = red color, The spectra shows --> green lines (inverse of red)

Na, Sodium = orange color, The spectra shows --> green lines (inverse of red)

K, Potassium = purple color, The spectra shows --> green lines (inverse of red)

Ca, Calcium = Red/orange color -- >The spectra shows --> Dark Blue+ Red lines

Strontium = Red --> The spectra shows --> Mostly green + green lines

Ba, Barium = Green --> The spectra shows --> Mostly red lines in the psectrum
