Chemical Bonds.
🎯 Your mission
Learn the rule. Then catch nature using it.
⚡ The twist
If it bubbles, something invisible is escaping.
Mind = Blown
💧 Hot water can freeze faster than cold water under the right conditions. Nobody fully understands why.
Make a hypothesis first
Guess: will the fizz be loud, soft, or none at all?
What You'll Learn
Two non-metal atoms share a pair of electrons so both reach a stable outer shell. Water has two single bonds, oxygen a double bond and nitrogen a triple. The bond itself is strong, but the forces between separate small molecules are weak.
