List the number of each type of atom on the left side of the equation 2Na3PO4(aq)+2CoCl2(aq)→2Co3(PO4)2(s )+6NaCl(aq)2Na3PO4(aq)+2CoCl2(aq)→2 Co3(PO4)2(s)+6NaCl(aq) Enter your answers separated by commas (the order of the numbers is the same as the order of the elements on the left side of the equation).

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
