Full video here: • What Is a Molecule?
A molecule is a group of atoms stuck together. They can vary greatly in size.
1. Hydrogen Molecules: Table for two (H₂)
The smallest molecule is two hydrogen atoms stuck together. Hydrogen is the lightest element. It pairs up with just one buddy to form a hydrogen molecule (H₂). That's just two atoms sticking together.
2. Water: The Popular Trio (H₂O)
Water is a molecule you know super well—it's everywhere! In every water molecule, there are three atoms: two hydrogen atoms (those same guys from the hydrogen molecule) and one oxygen atom. Together, they make every splash, drip, and drop!
3. Carbon Dioxide: The Bubble Maker (CO₂)
This molecule is famous for putting the fizz in your soda! Carbon dioxide has three atoms—one carbon and two oxygen atoms. They work together to make those bubbles that tickle your nose when you drink a soda.
4. Sugar: The Sweet Team (C₆H₁₂O₆)
Sugar molecules are like a little sports team. A sugar molecule, like glucose, has 24 atoms: 6 carbon, 12 hydrogen, and 6 oxygen atoms.
5. DNA: The Blueprint of Life
Now, here’s a giant! While single nucleotides of DNA are made of only about 40 atoms, millions of nucleotides are linked together to make a DNA chain. This means a full chain of DNA in one of your cells is made up of billions of atoms!
