Question

What is the molecularity of the elemental gases?

Answer 1

In fact all of the elemental gases, save the Noble Gases, are binuclear diatomic molecules........

Explanation:

`H_2`, `N_2`, `O_2`, `X_2` `(X=F, Cl)`..........

The atomic configuration of the element is LESS stable than the electronic configuration when the species forms an element-element bond in the binuclear molecule.

And so.....`Cl*+*ClrarrCl-Cl` etc......
