Atoms Jokes

From "New Scientist", attributed from R.D. Hayler, Stoke-on-Trent, Staffordshire, to a friend:
Two sodium atoms are walking along the street when one stops and says, "Oh my God, I think I've lost an electron!"
"Are you sure?" asks the other sodium atom.
"Yes," replies the first sodium atom, "I'm positive."

Two atoms are walking down the street when one atom says to the other, "I think I lost an electron."
The other atom says "Are you sure?"
"Yeah I'm positive!"

Two atoms were walking down the street. One atom says to the other one, "I've lost an electron!

The 2nd atom replies, "Are you sure?"

Says the 1st atom, "I'm positive."

Editor's note: I find it personally amusing that this joke is simultaneously an Intellectual joke, yet one of the stupidest jokes I've heard...

Two atoms are walking down the street when they run into each other. The first says to the second, "Are you all right? You
don't look so good." "I'm not feeling very well," says the second atom. "I lost an electron!" "Are you sure?" asks the first."Yeah, I'm positive!"

Professor Sokolsky was lecturing his Atomic physics class.He asked, "If molecules can be split into atoms and the atoms split into electrons, can the electrons be broken down any further?"
A pupil replied, "I'm not certain, but a sure way to find out would be to mail some of them in a Christmas package marked 'fragile'."
