positive charge
Monovalent metals are metals that can form ions with a charge of +1. Examples of monovalent metals include lithium (Li), sodium (Na), and potassium (K). These metals typically lose one electron to achieve a stable electron configuration.
Alkaline earth metals typically have a charge of +2 in their ionic forms, as they lose two electrons to achieve a stable electron configuration. This charge is a result of their tendency to form ionic bonds by losing two valence electrons.
Group 1 and Group 2 metals (alkali metals and alkaline earth metals) do not require their charge oxidation number specified in the names of ionic compounds they form. This is because they typically have a fixed charge that does not vary.
In the periodic table, alkali metals are located in group 1 and have a +1 ionic charge, while alkaline earth metals are in group 2 and have a +2 ionic charge. Aluminum is located in group 13 and typically has a +3 ionic charge. The group number can help you recall the typical ionic charge of these elements.
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.
Your Alkali Metals are those elements on the leftmost column of the periodic table (except for Hydrogen). Lithium (Li), Sodium (Na), Potassium (K), Rubidium, Cesium, Francium. You can remember them as those that form the Alkali bases, Sodium Hydroxide (NaOH), and Potassium Hydroxide (KOH) among others. In Pure Metallic form, they would have a neutral charge. However, they are frequently found in ionic form where they loose an electron to form a positive ion with a +1 charge. Li+ Na+ K+ etc.
Cations are positively charged ions that can be formed by both metals and non-metals. However, cations are more commonly associated with metals because metals tend to lose electrons to form positive ions.
Rubidium belongs to Alkali metals so its ionic charge is +1.

H2SO4 is an acid, not a metal and it does not contain any metals. In water it dissociates into H+ and SO42- ions with 1+ and 2- charges respectively.
Alkali earth metals typically form +2 ions when they lose two electrons to achieve a stable electron configuration (noble gas configuration).
