What are atoms?

Bianca Wiggins asked the Naked Scientists:
What are atoms? How do we know they exist? What are they made of?

What do you think?

Atoms are the building blocks of molecules and compounds so to speak, with a nucleus made of protons and neutrons (which are respectively made of up and down quarks), and electron orbitals dependant on their energy levels and number of protons amongst other things. There have been images produced by scanning tunneling or electron tunneling microscopes of atoms, as it is accepted that they exist.
