Rubidium , like sodium and potassium, is a Group (I) metallic element. Like sodium and potassium, it has only ONE valence electron, which it readily ionisses to become Rb^(+) cation.
Because it is further down the Group(I) it is more reactive than sodium or potassium, by that one electron ionising off extremely quickly, when reacting with water to liberate hydrogen , which in turn because of the energy release , the hydrogen ignites , with a violent bang.
If in an experiment, have the largest tank of water possible , the smallest (pin head sized), pellet of rubidium, a glass-screen, and preferably outdoors. Drop, using tongs, the pellet into the water from behind the screen, and it will instantaneously bang.
The atomic number of rubidium is 37. That means it has 37 protons and 37 electrons. After we fill in the first 37 orbitals with electrons, we get the configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1. Since 5 is the highest numbered shell, rubidium has 1 valence electron.
1 valence electron. It is an alkali metal and all alkali metals have one atom on their last energy level.
5s1, so one valence electron in the 5th shell
One. Sodium is found in Group 1, which is characterized by having one valence electron, so by extension, potassium, rubidium, cesium, and francium also have one valence electron.
For group 1 elements : lithium , sodium, potassium...etc All of them have one valence electrons , however Rubidium(Rb) have two valence electrons. Therefore, Cesium have one valence electrons. :D
Rubidium has one valence electron as it an alkali metal.
Rubidium has one valence electron in the 5s orbital.
2 Valence Electrons
The atomic number of rubidium is 37. That means it has 37 protons and 37 electrons. After we fill in the first 37 orbitals with electrons, we get the configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1. Since 5 is the highest numbered shell, rubidium has 1 valence electron.
Rubidium has one valence electron in the 5th energy level, while strontium has two valence electrons in the 5th energy level. Since rubidium has only one valence electron compared to strontium's two, the valence electron in rubidium is further from the nucleus. This is due to the increasing number of electron shells as you move down a group in the periodic table.
Rubidium is in group 1. The electron configuration is [Kr] 5s1. It has one valence electron.
Rubidium (Rb) has 1 valence electron. This is because it is in the first group (group 1) of the periodic table, which means it has 1 electron in its outermost shell.
This would be Sb - Antimony.
1 valence electron. It is an alkali metal and all alkali metals have one atom on their last energy level.
5s1, so one valence electron in the 5th shell
Yes. Rubidium is an alkali metal, and all alkali metals have one valence electron.
One. Sodium is found in Group 1, which is characterized by having one valence electron, so by extension, potassium, rubidium, cesium, and francium also have one valence electron.
