What are elements?

Everything around you is made up of elements, which are like the basic building blocks of stuff.

Think of it this way: if you have a toy box full of different kinds of blocks, some red, some blue, some square, some round, each kind of block is like an element. Just like how you can build many different toys by mixing and matching those blocks, scientists mix and match elements to make all the things in the world.

Imagine you have a bag of sugar. Sugar is made from just a few kinds of elements, mostly carbon, oxygen, and hydrogen. These are like the special ingredients that make sugar sweet.

Now think about your favorite crayon. Crayons are made of wax and pigments, which come from other elements, like sulfur or iron.

Each element has its own unique identity, just like how each block in the toy box is different. When scientists put these elements together, they can make all kinds of things: water, metal, even you!
