Non-metals generally exhibit low luster compared to metals, which possess a characteristic shiny and reflective surface. The term “luster” refers to the amount of light that reflects off a mineral’s surface. Metals, such as gold and silver, have high luster because their tightly packed electrons scatter light effectively. Conversely, non-metals, such as carbon and sulfur, have loosely bound electrons that do not reflect light as well, resulting in a lower luster appearance. However, there are exceptions to this generalization, with some non-metals possessing a vitreous or adamantine luster, which resembles the shiny appearance of glass or diamonds.
