Match the elements given in Column-$I$ with the colour they impart to the flame given in Column-$II$.
Column-$I$ Column-$II$ $A$. $Cs$ $1$. Apple green $B$. $Na$ $2$. Violet $C$. $K$ $3$. Brick red $D$. $Ca$ $4$. Yellow $E$. $Sr$ $5$. Crimson red $F$. $Ba$ $6$. Blue
| Column-$I$ | Column-$II$ |
|---|---|
| $A$. $Cs$ | $1$. Apple green |
| $B$. $Na$ | $2$. Violet |
| $C$. $K$ | $3$. Brick red |
| $D$. $Ca$ | $4$. Yellow |
| $E$. $Sr$ | $5$. Crimson red |
| $F$. $Ba$ | $6$. Blue |
(A-6, B-4, C-2, D-3, E-5, F-1) The correct matches are: $A-6, B-4, C-2, D-3, E-5, F-1$.
This occurs because the heat from the flame excites the outermost orbital electron to a higher energy level.
When the excited electron returns to the ground state,it emits radiation in the visible region,imparting a characteristic colour to the Bunsen flame.
