All the elements in the first column of the periodic table have 1 valence electron.They include: lithium (Li), sodium (Na), postassium (K), rubidium (Rb),cesium (Cs), and Francium (Fr).See the Related Questions for more information.
Rb- RubidiumCr2O7 - dichromateRubidium dichromate
These are the ions and their charges: Rb+1 N-3The charges have to add up to zero, so two +1 Rb ions were added to cancel out the -3 charge of N: Rb+1 Rb+1 Rb+1 N-3Simplify: Rb3N
Lithium, Rubidium, Cesium, Francium. Li , Rb , Cs, and Fr
Since Rb forms a 1+ ion the formula for rubidium oxide is Rb2O.
Rubidium has one valence electron in the 5s orbital.
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 5s electron.
Rb is the symbol for the element, rubidium.
Sb has 5 valence electrons, In has 3, Rb has 1 valence electron and Xe has 8. So in ranking, it would be, Xe, Sb, In, Rb.
Rubidium (Rb) has a +1 ion, will have the same electron configuration as krypton (Kr) because the +1 status means it has lost an electron. The configuration is written 1s22s22p63s23p64s23d104p6.
1: This is the correct answer for any element in wide form Periodic Table Group 1.
Rubidium is a group 1 metal with just one valence electron. It therefore forms the ion Rb+ as it loses the electron. The ionic formula is Rb+ Cl-
There is actually 37 Protons in Rb (Rubidium). Also there is the same number of protons as electrons. So 37 for protons and electrons. (: Your welcome little kid.
Rubidium has only one valence electron which it loses easily to form the Rb+ ion. When rubidium atoms come in contact with water, they hive up those electrons to the water molecules, reducing them to hydroxide ions (OH-) and hydrogen gas (H2)
