Group one element five is rubidium, which is a highly reactive alkali metal.
Chemical characteristics:
1. Rubidium readily reacts with water to form rubidium hydroxide and hydrogen gas.
2. It can also react with oxygen to form rubidium oxide.
3. Rubidium can form compounds with halogens, such as rubidium chloride and rubidium fluoride.
4. It has a strong affinity for sulfur, forming rubidium sulfide.
5. Rubidium can also form alloys with other metals, such as rubidium-iron alloy.
Physical characteristics:
1. Rubidium is a soft, silvery-white metal that is easily cut with a knife.
2. It has a melting point of 39.3°C and a boiling point of 688°C.
3. Rubidium is a solid at room temperature and pressure.
4. It has a density of 1.532 g/cm3.
5. Rubidium is a highly conductive metal, both electrically and thermally.
