Magnesium metal does not burn in the vessel containing_______________?
Correct answer: D. Ne
- A. N2
- B. O2
- C. N2 and O2
- D. Ne
Explanation
Magnesium does not burn in neon because neon is chemically inert and does not support combustion. Magnesium burns in oxygen and can also react with nitrogen when strongly heated, so students may choose nitrogen by assuming all gases other than oxygen prevent burning.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
