What is the Ionic Charge of Rubidium (Rb)? And Why?
Elements of group 18 have 0 ionic charge, Now here our element is Rubidium (Rb) which lies in group 1 of the periodic table. Hence the ionic charge of Rubidium (Rb) is 1+. Note: The blank area shown in the above periodic table are mostly the transition and post-transition elements. They show variable ionic charge.
Rubidium (Rb)
Rubidium is a group 1 element and it has bigger atomic size compared to the elements of other groups. Also it possesses only one electron in the outermost orbit. It has a very less Ionization energy, that means very less energy is required to remove the valence electrons from its orbit. Also, Rubidium has lower melting point and lower boiling ...

Atom Calculator
Find the number of protons (atomic number). Find the number of neutrons by subtracting the number of protons from the mass number. Add the protons and neutrons. Omit the electrons, as their combined mass is very small compared to the mass of the nucleus. Congratulations! Now you have the atomic mass of that atom.
Why is Rubidium-87 used for Bose-Einstein condensates?
11. Rubidium-87 was the first and the most popular atom for making Bose–Einstein condensates in dilute atomic gases. Even though rubidium-85 is more abundant, rubidium-87 has a positive scattering length, which means it is mutually repulsive, at low temperatures. This prevents a collapse of all but the smallest condensates.
Wikijunior:The Elements/Rubidium
Rubidium is used in some fireworks, for its color. It is also used for various high-tech devices. It is used in vacuum tubes as a getter, a material that combines with and removes trace gases from inside the tubes, to keep the inside of the tube a vacuum. It is used in lasers and high-precision clocks.

Rubidium, Physical and Chemical Properties | SpringerLink
Rubidium is a very reactive soft metal with a silvery luster and has the typical chemical properties of an alkali metal. It is more abundant in the Earth''s crust than lithium and cesium. Due to the similarity in their ionic radii, rubidium is always found in potash salt deposits, e.g., carnallite, sylvite, and langbeinite, which contain 10–300 g/t rubidium oxide.
Which statement correctly compares the number of protons and electrons in atoms of rubidium …
Rubidium posseses a nucleus that consists of 37 protons and 37 electrons while Calcium posseses 20 protons and 20 electrons. Therefore, the statement that correctly compares the number of protons and electrons in atoms of rubidium (Rb) and calcium (Ca) is that Rubidium has more protons and more electrons than calcium.
