Correction: The answer Leonard gives to Penny is actually a correct scientific statement, and it doesn't indicate that he's clueless. He says "kinda like carbon atoms for a benzene ring, proximity and valence electrons". This is a correct statement. Carbon atoms are small and have 4 valence electrons, i.e., they can form 4 bonds. Due to catenation, carbon atoms have a very strong tendency to bond with other carbon atoms. Similarly, Leonard's statement suggests that they worked at the same place (hence proximity) and they were all seeking friends (valence electrons). Hence they became friends.
