An element is highly conductive, highly reactive, soft, and lustrous. The element most likely belongs to which group?
The element most likely belongs to Group 1, also known as the alkali metals. This group includes elements such as lithium (Li), sodium (Na), and potassium (K), which are highly conductive, highly reactive, soft, and lustrous.
How does mercury differ from other metals?
Mercury differs from other metals in several ways:
1. State: Mercury is the only metal that is liquid at room temperature. Most other metals are solid at room temperature.
2. Density: Mercury is also much denser than most other metals. Its density is 13.5 grams per cubic centimeter, making it one of the densest common elements.
3. Reactivity: Unlike most metals, mercury is not very reactive with air or water. It forms a thin oxide layer on its surface, which protects it from further oxidation. This low reactivity allows mercury to remain in its liquid state and not corrode easily.
4. Toxicity: Mercury is highly toxic to humans and many other organisms. It is one of the few metals that can penetrate the skin and enter the bloodstream, which can cause severe health issues.
Due to its unique properties, mercury has various applications, including use in thermometers, barometers, electrical switches, and dental fillings. However, its toxicity has led to strict regulations on its usage and disposal.
