Why Magnesium is colourless in a flame test?
Option: 1
Because of its basicity.
Option: 2
Because of 2 unpaired electrons.
Option: 3
Because of no unpaired electrons.
Option: 4
Because of its small size.
Answers (1)
has a small size and tightly bound electrons. So, the energy required to remove the electron is too high and it absorbs in the UV spectrum. So, it appears colourless.
Hence option 4 is correct.
