Rubidium Ionic Charge and Bonding

The video explains the ionic charge of rubidium (Rb) when it forms ionic bonds. Rubidium, located in group one of the periodic table, forms ions with a charge of one plus (Rb+). The video describes how rubidium loses an electron to form a positive ion and how this interacts with negative ions to create ionic bonds. The explanation is supported by the periodic table's general pattern for ionic charges.
