Why do beryllium and magnesium not impart any color to a flame during a flame test?
Options
- AThey have low ionization energies
- BThey have strongly bound electrons
- CThey have high melting points
- DThey have small atomic sizes
Correct answer
B. They have strongly bound electrons
Step-by-step solution
Beryllium and magnesium have electrons that are too strongly bound to get excited by a flame, so they do not impart any color to the flame during a flame test.
