Because they are extremely reactive to any moisture in the air.
See the Related Questions about the reactivity of the alkali metals (rubidium and cesium are the most reactive of the alkali metals).
Sulfuric acid should be stored in a cool, well-ventilated area away from sources of heat or ignition. It should be kept in a tightly sealed container made of a chemically resistant material like polyethylene or glass. Additionally, it should be stored separately from incompatible materials to prevent reactions or spills.
Acids are kept in glass containers because glass is resistant to corrosion from acidic substances and does not react with the acids, ensuring they remain contained securely. This helps prevent any chemical reactions or leaks that could occur with other materials, such as metal or plastic, when in contact with acids. Glass containers are also transparent, allowing for easy observation of the contents.
Hydrofluoric acid is an acid that cannot be kept in glass containers because it reacts with silica in the glass to form silicon tetrafluoride and water, weakening the container and potentially causing it to break. This reaction can release toxic fumes and lead to leaks.
Hydrochloric acid should be stored in a cool, dry, well-ventilated area away from incompatible substances such as bases and metals. It should be kept in a tightly sealed container made of acid-resistant material, such as glass or certain plastics. Proper labeling and handling procedures should be followed to prevent accidents.
Bromine is typically stored in specially designed containers made of glass or plastic that are sealed tightly to prevent exposure to air or moisture. It is often kept in cool, dark areas away from sources of heat and light to prevent decomposition. Additionally, bromine should be stored in a well-ventilated area to avoid the build-up of potentially hazardous vapors.
Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium are the main alkali metals, which all react fairly spectacularly with water (Cesium must be kept in argon gas to stop it reacting with air).
Rubidium and cesium are highly reactive and should be stored in airtight containers away from air and moisture in a cool, dry place. It is recommended to store them in a non-reactive container, such as glass or certain types of plastic, in a well-ventilated area. Additionally, they should be kept isolated from other reactive substances.
Francium melts at about 80oF. Cesium melts at about 83.4oF. Gallium melts at about 85.6oF. All of these are solid at room temperature but would melt in your hand. Rubidium melts at about 103.4oF, so that is just a little higher than body temperature. Mercury melts at 37.7oF, so it would certainly melt in your hand, but it would already be a liquid at room temperature.
agers! if you keep it sealed like, golden virginia, it can last months!
Yes, a reaction occurs between rubidium and lithium chloride. When rubidium metal comes into contact with lithium chloride, a single displacement reaction takes place where rubid破um replaces lithium in lithium chloride, forming rubidium chloride and lithium metal.
1wk if kept sealed and in the fridge always unless to be eaten... 6months if kept frozen... =)
No dragonflys should be out in the open there can be no advantage in such cruelty.
Felonies are kept for life. You can have them sealed if you go through the proper channels. Misdemeanors are usually kept for 7 yrs, in Florida anyway. They stay sealed unless you are tried for another big crime. Then theyre used to prove a case against you. You know, for character purposes.
No they should be kept in a hutch or a cage.

yes, but it needs to be kept in a sealed container with no light
Its kept in a museum in Paris, inside a glass case with the temperature inside the case kept the constant.
