Detailed Solution

The noble gases exist as monatomic elements with values,

$Δ_{1} H_{1} = 2372 Δ_{1} H_{2} = 5251,, Δ_{e g} H = - 48 (in kJ {mol}^{- 1})$

For instance, the strongest common oxidising agent is elemental fluorine with values,

$Δ_{1} H_{1} = 1681 Δ_{1} H_{2} = 3374,, Δ_{e g} H = - 333 (in kJ {mol}^{- 1})$

Helium is the least reactive of the non-metallic elements with values,

$Δ_{1} H_{1} = 1008 Δ_{1} H_{2} = 1846, Δ_{e g} H = - 295 (in kJ {mol}^{- 1})$
