Distinguishing Atoms from Elements

The video tutorial explains the difference between elements and atoms using an analogy with apples. It introduces the concept of elements from the periodic table, focusing on carbon and its atomic structure. The tutorial discusses the varieties of carbon atoms, known as isotopes, which differ in the number of neutrons. The video concludes with definitions of key terms and a summary of the differences and commonalities between elements and atoms.
