in the F₂ molecule bond order is equal to 1. but in F₂⁺² bond order is equal to 2. if bond order increases stability of bond increases. so F₂⁺² is stronger bond comparing to F₂. that means in F₂ we have only single bond. but in F₂⁺² double bond. bond order indicates number of covalent bonds present in the molecules.
