A chemical compound is like a recipe for making something new, like a cake. You need to mix different ingredients together in specific amounts to make the cake. In the same way, a chemical compound is made up of different kinds of atoms that are combined together in specific ratios.
Atoms are like different types of building blocks. They are really tiny and cannot be seen by our eyes. Elements are made up of only one type of atom, and can be found on the periodic table.
For example, if you mix two hydrogen atoms and one oxygen atom together, you get a new substance - water! This is a chemical compound.
Chemical compounds can have different properties than the elements they are made up of. For instance, sugar and salt are both made of different types of atoms, and have different tastes and textures than the individual atoms themselves.
Scientists use chemical compounds to make new materials, drugs, and other useful products.
