how are atoms and elements related?

Answer 1

Atoms have different types (or flavors, if you like). Each atom with the same number of protons has the same characteristics as all other atoms with that number of protons. So, we group atoms by how many protons they have. If an atom has 1 proton, it is hydrogen. If it has 2 protons, it is helium. If it has 8 protons, it is oxygen, and so on. These are the elements.

There are about 90 elements that are found naturally on Earth. Everything you see on Earth is made of these elements, stuck together in different ways.

Answer 2

All elements have a specific number of atoms.
