Even though these two have the same chemical formula, they both crystallize differently, causing them to be classified as different minerals. Sharing the same chemical formula causes these two minerals to be mislabeled, since their physical characteristics are so similar, and the only real way to definitively tell them apart is by complex analysis.…

Gold is widely used in modern day medicine to treat disorders. This is because gold is very resistant to bacteria. Bacteria are microscopic single-celled organisms. Bacteria are prokaryotes, meaning the entire organism consists of a single cell with a simple internal structure. The DNA of a prokaryote is neatly packed in the nucleus. The bacterial DNA floats freely in a twisted thread-like mass called the nucleoid. Gold is unaffected by almost everything. The only materials that can affect gold…
