Atomic properties

Question 1

Atomic radii of noble gases

Answer 1

Atomic Radii
- Increases down the group due to increase in atomic umber

Question 2

Ionization enthalpy of Noble gases
Why do noble gases have very high ionization enthalpy?

Answer 2

Ionization enthalpy of noble gases DECREASES down the group due to increase in atomic size

Noble gases have very high Ionization enthalpy
Reason- Stable electronic configuration

Question 3

Electron Gain enthalpy of noble gases
Write the order of electron gain enthalpy
Noble gases do not have the tendency to accept electrons. Why?

Answer 3

Electron Gain Enthalpy - DECREASES down the grp
Order- Ne>Ar=Kr>Xe>Rn>He

Noble gases have no tendency to accept electrons
Reason- Stable configuration
Therefore, Have large value of +ve EGE
