Rubidium is a metal element. There are 37 electrons in a single atom.
The ionic charge for Rb (Rubidium) is typically +1. Rubidium belongs to Group 1 of the periodic table, also known as alkali metals, which typically form ions with a +1 charge.
Rubidium triiodide = RbI3It can also be written as Rb[I3]
The ionic formula for rubidium ion (Rb+) and nitride ion (N3-) would be Rb3N. The charges on the ions must balance out to create a neutral compound.

Rubidium (Rb) typically has a positive charge. As an alkali metal in Group 1 of the periodic table, it readily loses one electron to achieve a stable electron configuration, resulting in a +1 charge (Rb⁺) when it forms ions. In chemical reactions, rubidium usually participates as a cation.
When Rb2O and CaCl2 are added together, the resulting spectator ions are Cl^- and Rb^+ ions. This is because the Rb^+ ions from Rb2O do not participate in the reaction, and the Cl^- ions from CaCl2 similarly remain unchanged. The reaction forms CaO and RbCl as the products.

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
The ionic formula for rubidium ion (Rb+) and nitride ion (N3-) would be Rb3N. The charges on the ions must balance out to create a neutral compound.

The charge of sulfate ions is 2-.
Such ions are called cations. They are usually individual metal atoms that have lost one or more electrons from their outermost shell. This loss of electrons (and thus a loss of negative charge) produces a slight positive charge on the remaining ion, e.g Li+, Rb+, Mg++, Ba++, Fe++, Fe+++. Notice that all of these ions are atoms from the metal section of the Periodic table, the centre, the lower, and the left hand Such ions are called cations.

The charge of nitrate ions is -1.
On their own metals have no charge. Metal ions have a positive charge.
