Assertion (A): Magnesium does not impart any characteristic colour to the flame.
Reason (R): Due to small size and high effective nuclear charge, magnesium requires a large amount of energy for excitation of electrons.
(A) Both A and R are true and R is the correct explanation of A.br(B) Both A and R are true, but R is not the correct explanation of A.
(C) A is true, but R is false.
(D) A is false, but R is true.
