7) Anabella, Kylee, Jeremiah, and Madyx were doing laundry. They wondered if bleach (NaOCl) was an atom, element, or compound? Bella argued that Na, O, and Cl were atoms that formed into elements to make the compound of NaOCL. Kylee and Jeremiah said that Na was a non-metal, O was a metalloid, and Cl was a metal. Madyx believed that Na had luster, O was ductile, and Cl was malleable. Who is right? Why? Explain with evidence (Use your notes, Google, Periodic table, slideshow)
