Potassium's Tear

This is a pun. The joke plays on the element names 'potassium' and 'argon'. The setup asks why potassium would cry and the punchline is that "all of his friends argon", which sounds like "all of his friends are gone". It's a play on words.

• Why did the electron leave the atom? Because it wanted to be Argon.
• I was gonna tell you a sodium joke, but Na, only I thought it was so dium funny.
• I would say a good joke, but all the good ones Argon.
• Oxygen and potassium went on a date. I heard it was OK.
