The molecular equation is 2KOH(aq) + CoBr2(aq) ==> 2KBr(aq) + Co(OH)2(s)The spectator ions are K^+ and Br^-
In water solution potassium ion (K+) is a spectator ion, it does not react because both KOH and KBr are soluble salts (the first strongly basic, the last a neutral salt)
NO3- is a spectator ion.
The ionic equation is 2K+(aq) + 2OH-(aq) + Co^2(aq) + 2Br^-(aq) ==> 2K+(aq) + 2Br-(aq) + Co(OH)2(s)net ionic equation is Co2+(aq) + 2OH-(aq) ==> Co(OH)2(s)So spectators are K+ and Br- ions.
in most reactions it is, however if it is said that it is a liquid solid or gas it is not a spectator ion
A spectator ion is an ion that does not take part in the reaction. If you write out a normal equation. look for something that is the same on both sides and does not change state. This is a spectator ion and can be crossed out of the net ionic equation

Co2+ is an ion. But it will combine with any anion to form a compound as in CoCl2 or CoBr2.

K+ and NO3- because KOH + HNO3 (yields) H2O + KNO3
Which is a spectator ion in the reaction between Na2CO3(aq) and HNO3(aq)
The symbol for a potassium ion is K+ The charge is +1 because potassium is in the first group on the periodic table.
This depends on the reaction.
When KOH is placed in water, it ionizes to K+ and OH-, so the polyatomic ion is the OH- (hydroxyl anion).
