The clip belongs to a series of short songs credited to Profe Guadarrama, a teacher whose classroom recordings are tagged with chemistry and the periodic table. Labeled as the sixth song, it appears to be one of several study aids made to help students remember elements through music. With only a small audience so far, it circulates mainly among students and followers of the teacher's lessons, who replay the catchy verses while studying. Its continued use comes from that practical purpose: a memorable melody makes dry chemistry facts easier to recall.
