Certainly! Here's a breakdown of the elements listed as metals, metalloids, or nonmetals:
- Seaborgium (Sg): Seaborgium (Sg) is a synthetic element, which means it is man-made and not found naturally in the environment. Since it is a metal and falls into the category of transition metals, Seaborgium can be classified as a metal.
- Selenium (Se): Selenium (Se) is a nonmetal. It is commonly found in nature and is used in various applications such as electronics and glassmaking.
- Gold (Au): Gold (Au) is a metal. It is a highly sought-after precious metal known for its luster, density, and resistance to corrosion.
- Astatine (At): Astatine (At) is a nonmetal. It is a highly radioactive element and is considered the rarest naturally occurring nonmetal.
- Krypton (Kr): Krypton (Kr) is a noble gas, which falls under the category of nonmetals. It is a colorless and odorless gas commonly used in lighting.
- Mercury (Hg): Mercury (Hg) is a metal. It is the only metal that exists in a liquid state at room temperature and is known for its high density.
In summary:
- Metals: Seaborgium (Sg), Gold (Au), Mercury (Hg)
- Nonmetals: Selenium (Se), Astatine (At), Krypton (Kr)
