Question

Beryllium and magnesium do not impart any colour to the flame test. The reason behind this is (A) lower value of ionisation energy (B) higher value of ionisation energy (C) larger size of alkaline earth metal (D) Both (b) and (c) are correct

Tardigrade Admin · Accepted Answer

The electrons in beryllium and magnesium are so tightly bounded with nucleus that they do not get excited by flame. This is because, these metals also have higher value of ionisation energy.
Hence, these metals do not impart colour to flame test.

Q. Beryllium and magnesium do not impart any colour to the flame test. The reason behind this is

lower value of ionisation energy

higher value of ionisation energy

larger size of alkaline earth metal

Both (b) and (c) are correct

The electrons in beryllium and magnesium are so tightly bounded with nucleus that they do not get excited by flame. This is because, these metals also have higher value of ionisation energy. Hence, these metals do not impart colour to flame test.
