Question

What are spectral terms for the normal and excited state of Mercury(Hg).What are all transitions? ​

Answer 1

Mercury spectral terms have been shown for normal and excited state.

Explanation:

• The spectral terms show evidence for electrons moving from one energy level to another within one atom.  
• The successive ionisations of the atom is indicative of the energy transfer within the energy shells. There is a large energy difference between the shells.  
• Atom of mercury have 80 electrons, in the outer shell structure is  2.8.18.32.18.2.
• The mercury electrons will not accept energy unless it reaches a threshold for being in an excited state.  
• 4.9 Volt of potential difference is required to correspond an ultraviolet emission of mercury spectrum of 254 nm.
