It's a lot of fun, but rubidium is a metal and a solid.
Edit:
That's not the whole story. Rubidium is quite easy to vaporize. In fact, it is often used in its gaseous form to show hyperfine splitting of energy levels.
So Rb is not normally a gas in nature but it is regularly used in the gas form.
Rubidium reacts violently with water to create Rubidium Hydroxide and hydrogen gas. The gas may ignite with the heat of the reaction. The Rubidium Hydroxide remains in solution in the water, and is very strongly alkaline - i.e. it is a base.2Rb(s) + 2H20(l) ---> 2RbOH(aq) + H2(g)
Rubidium is more reactive than krypton. Rubidium is an alkali metal and reacts vigorously with water, while krypton is a noble gas and is inert under normal conditions.
how is the reactivity for ptassium
The word equation for the reaction of rubidium with water is rubidium + water --> rubidium hydroxide + hydrogen. Rubidium is a metal that reacts very quickly and fiercely, even explosively with water.
The reaction between rubidium and water is highly exothermic, leading to the spontaneous production of hydrogen gas and the formation of rubidium hydroxide. This exothermic reaction is typically very vigorous and can even result in the ignition of the hydrogen gas produced.
No.
Rubidium reacts violently with water to create Rubidium Hydroxide and hydrogen gas. The gas may ignite with the heat of the reaction. The Rubidium Hydroxide remains in solution in the water, and is very strongly alkaline - i.e. it is a base.2Rb(s) + 2H20(l) ---> 2RbOH(aq) + H2(g)
When rubidium is put in acid, it reacts and forms rubidium ions and hydrogen gas. This reaction is violent and can release a significant amount of heat and gas. Precautions should be taken when handling this reaction as it can be hazardous.
The noble gas core configuration of rubidium is [Kr]5s1. It is derived from the electron configuration of the noble gas krypton ([Kr] = 1s22s22p63s23p63d104s24p6), followed by the valence shell configuration of rubidium (5s1).
Hydrogen.
Rubidium is more reactive than krypton. Rubidium is an alkali metal and reacts vigorously with water, while krypton is a noble gas and is inert under normal conditions.
Rubidium has an atomic number of 37, making it an alkali metal. This means that its last shell is an s with only one electron. The full notation is [Kr] 5s1.
[Kr] 5s1

Rubidium is a solid at room temperature and pressure. It has a melting point of 39.3°C (102.7°F) and a boiling point of 688°C (1270°F), so it can exist in liquid and gaseous forms at higher temperatures.
