Assertion (A): Ba, Ca and Sr produces individual characteristic colour to flame test. Reason (R): this is due to excitation of loosely held electrons from outermost orbit to excited state of orbital.
A.Both A and R are correct; R is the correct✓ Correct
B.Both A and R are correct; R is not the correct
C.A is correct; R is incorrect
D.R is correct; A is incorrect
Explanation
Ba, Sr, Ca produces individual colour to flame test due to excitation of loosely held electron from valence shell to excited state orbit which when comes to its original ground state emits radiation of appropriate energy.
