What is the noble gas core configuration of rubidium?
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).
What is the nearest noble gas of rubidium?
The nearest noble gas to rubidium is krypton. Rubidium, which has the atomic number 37, is located in group 1 of the periodic table, while krypton, with the atomic number 36, is found in group 18. Krypton is one period above rubidium, making it the closest noble gas in terms of atomic number.
What is the noble gas configuration of rb?
[Kr] 5s1
What is the Noble gas notation of rubidium?
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.
What is more reactive rubidium or krypton?
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.
What is the correct noble gas configuration for Rb?
[Kr]5s1 would be the noble gas electron configuration for Rb.
Is rubidium in water an acid or a base?
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)
What is the atomic number of the element with the noble gas notation kr 5s1?
The noble gas notation "Kr 5s1" indicates that the element has one electron in the 5s subshell, following krypton (Kr), which has an atomic number of 36. Therefore, the atomic number of the element is 37, which corresponds to rubidium (Rb).
What happens to rubidium when its put in acid?
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.
Is rubidium a metal or non metal?
No, rubidium is not considered a transition metal. It is not located in the periodic table where the other transition metals are, which is mainly the d-block.
Is krypton halogen noble gas or neither?
No, it is a noble gas
What gas is produced when rubidium and water react?
Hydrogen.
