Since Rb forms a 1+ ion the formula for rubidium oxide is Rb2O.
There are no neurons in an atom of 82 Rb. Neurons are specialized cells found in the nervous system of living organisms, while atoms of rubidium-82 (82Rb) are composed of protons, neutrons, and electrons.
Rubidium forms a +1 cation (Rb+) by losing one electron to achieve a stable electron configuration. Rubidium has one valence electron in its outermost shell, so by losing this electron, it becomes a cation.
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
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.
Rubidium has one valence electron in the 5s orbital.
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.

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.
Rb is the symbol for the element, rubidium.
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
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.
1: This is the correct answer for any element in wide form Periodic Table Group 1.
Each atom of Rubidium (Rb) has 37 protons.
In the Rb atom, the electron configuration is [Kr]5s^1. This means there is 1 electron in the 5s sublevel of the Rb atom.
When rubidium (Rb) and phosphorus (P) bond ionically, they form the compound rubidium phosphide, and it has the formula Rb3P. This is because rubidium has a charge of +1 during bonding (because of its 1 valence electron) and phosphorus has a charge of -3 (because of its 5 valence electrons - see "octet rule.") Thus, it takes 3 rubidiums to satisfy phosphorus' need for 3 electrons. It is incorrect to call this compound "rubidium tri-phosphide," because this scenario is the only way those two elements can bond, so any prefixes would be redundant. In the naming of ionic compounds, the cation comes first, and its name is unchanged, but the anion gains the suffix "-ide."
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-
