Give the coordination number and the charge of the central metal ion in each coordination compound: For the charges, enter your answers with the correct sign. e. g. if you think the answer is +1, enter the positive sign followed by the number 1. Na2[Zn(OH)4] coordination number = charge = K[Co(H2O)2(C2O4)2] coordination number = charge = [Ru(H2O)2(NH3)2Cl2]Br coordination number = charge =
