1) :hover is a pseudo class, not a pseudo element.
2) Pseudo classes (in general) reflect some state or attribute of the element that isn't otherwise (easily/reliably) detectable in CSS. Pseudo elements represent some structure of the document that isn't part of the DOM.
3) Being hovered over is a state, a click is an event.

There is the :active pseudo class which may well apply while something is being clicked on (provided a click "activates" it, which is not defined by CSS currently, though there was work in this direction a while back).

Having said all that, while a :click pseudo class doesn't really work (neither does a ::click pseudo element), there are use cases for triggering transitions and animations on events. We've discussed this also in the past but haven't gotten any good answers yet.
