Question

Explain why ionization energy of mercury is compare to the noble gas?

Answer 1

Answer:

So you can see that like Beryllium, it is also have a completely filled s orbital. Also an atom is more stable if the orbitals are half filled or completely filled. So it is reluctant to loose the electron. Hence Mercury has a high ionization energy.

Answer 2

The ionization energy of mercury is comparable to that of noble gases.

• Both noble gases and mercury is having very high ionization energy.
• Elements with stable octets are said to be having high ionization enthalpy.
• Noble gases have a stable octet and hence high ionization energy.
• In mercury due to the poor shielding effect of f orbitals, the nucleus exerts a more attractive force on electrons.
• Ionization energy is the energy required to remove the most loosely bound electron.
• Due to greater attraction of nucleus ionization energy is high for mercury.
• So both noble gases and mercury have high ionization energy.
