Universe's Filing Cabinet
What is the periodic table and how is it organized?
Imagine a giant filing cabinet where the universe keeps every single ingredient it owns. Not paint, not food, not LEGO bricks — but the actual stuff everything is made of. That cabinet exists, and we call it the periodic table.
Each drawer holds one element — one pure kind of atom that can't be broken down into anything simpler. There are about 118 of them. Some you know by heart: oxygen, gold, iron, carbon. Some you've probably never met, like seaborgium or oganesson, which sound like wizard spells.
