1 valence electron. It is an alkali metal and all alkali metals have one atom on their last energy level.
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.
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
Indium has 3 valence electrons.
Rubidium has one valence electron as it an alkali metal.
Rubidium has one valence electron in the 5s orbital.
2 Valence Electrons
Rubidium is in group 1. The electron configuration is [Kr] 5s1. It has one valence electron.
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 (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.
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.
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.
This would be Sb - Antimony.
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
Indium has 3 valence electrons.
