An Atom is a small molecule like a blueberry, they surround you everywhere. Today in class we talked about atoms mr.Calvert said “an atom is just like a blueberry, and a grapefruit is earth”. I think that mr.Calvert said this to explain a fun way to talk about atoms he said that “Atoms are made of three things protons,neutrons and electrons”. Another fact is that an is the smallest element on the periodic table.
