Electron

What did the scientist’s cat say? I think I’ve lost an electron, I’m pawsitive!
An atom loses an electron...
It says, "man, I really gotta keep an ion them."
I’m positive I just lost an electron.
Better keep an ion that.
Two sodium atoms are walking down the street. Suddenly one says “Oh, my God, I’ve lost an electron!” The other says “Lost an electron! Are you sure?” and the first replies “Yes, I’m positive!”
