How are rubidium and cesium stored?
Rubidium and cesium are both highly reactive alkali metals and must be stored in airtight containers to prevent them from reacting with moisture and oxygen in the air. They are typically stored under a layer of mineral oil or kerosene to prevent contact with air. Additionally, they are often kept in a cool, dry place to minimize the risk of spontaneous combustion. Proper handling and storage of rubidium and cesium are essential to ensure safety and prevent accidents. **
What is the shell model for rubidium?
The shell model for rubidium is based on the arrangement of its electrons in energy levels or shells. Rubidium has 37 electrons, with the electron configuration of [Kr] 5s1. This means that rubidium has a full inner shell of electrons (from the noble gas krypton) and one valence electron in the outermost shell. This configuration makes rubidium an alkali metal, which is highly reactive due to its tendency to lose that single valence electron. **

What is the reaction equation of rubidium hydroxide with water?
The reaction equation of rubidium hydroxide with water is: RbOH + H2O → Rb+ + OH- + H2O. In this reaction, rubidium hydroxide dissociates into rubidium ions (Rb+) and hydroxide ions (OH-) in water. **

Why are there 16 electrons on the third atomic orbit of the rubidium atom?
The third atomic orbit of the rubidium atom can hold up to 18 electrons according to the Aufbau principle, which states that electrons fill orbitals starting with the lowest energy level. Rubidium has 37 electrons, so the first and second orbits are filled with 2 and 8 electrons, leaving 27 electrons for the third orbit. However, due to the electron configuration of rubidium, the third orbit only holds 16 electrons, as the remaining 11 electrons are placed in the fourth orbit. **
Why is the melting point of sodium, at 9772 °C, higher than that of rubidium, at 3931 °C?
The melting point of a substance is determined by the strength of the forces holding its particles together. In the case of sodium and rubidium, both are alkali metals with similar metallic bonding. However, sodium has a smaller atomic radius and a higher nuclear charge compared to rubidium. This results in stronger metallic bonding in sodium, requiring more energy to overcome and thus a higher melting point compared to rubidium. **
Why is the melting point of sodium higher at 9772 °C than that of rubidium at 3931 °C?
The melting point of a metal is determined by the strength of the metallic bonds holding the atoms together. In the case of sodium and rubidium, sodium has a higher melting point because it has a smaller atomic radius and a higher nuclear charge compared to rubidium. This results in stronger metallic bonds in sodium, requiring more energy to break them and melt the metal. Additionally, sodium has a higher density than rubidium, which also contributes to its higher melting point. **
