Isildur was not exactly a slouch. I imagine that Elrond would have had quite a fight on his hands to take it from the King of the Dunedain by force.

The real reason, of course, that Elrond did not take the ring from Isildur, is that Tolkien didn't want him to. He wanted to write a longer story.

But throwing that aside, as we can ;~D, I have speculated about the how the fact that Elrond was a ring bearer, the keeper of one of the three elven rings, would impact his ability to take and destroy the One.

On the surface, it would give him power. What kind of power, I am not sure of. I can look that up if others don't know.

But would it also make him unable to act against the One? - or the wielder of it? Tolkien didn't broadcast the fact that Elrond and Gandalf both bore those rings, but what would be your instinct be on how it would change the confrontation between the two?

Did Elrond even have his ring at that point? I believe it was Gil-galad's, so he would have inherited it from the dead Elven King. When this took place I do not know. I have no idea what effect having a ring of power would have. Gandalf and Galadriel had rings of power too, and they both refused to take the One Ring. In fact Gandalf only touches the One Ring before he knows what it is; once he knows what it is, he won't risk touching it at all. That probably says all that needs to be said on that topic.
