Final answer:
The name of the binary ionic compound pd3n4, containing a transition metal, is palladium(IV) nitride, where palladium has a +4 oxidation state.
Step-by-step explanation:
The binary ionic compound containing a transition metal, pd3n4, follows naming conventions that include the oxidation state of the transition metal. Palladium (Pd) can exhibit multiple charges, but in this compound, we must determine the charge based on the stoichiometry and the known charge of nitrogen (N). Nitrogen typically has a charge of -3, and there are four nitrogen atoms, totaling -12. Since the compound is electrically neutral, the combined charge of the three palladium atoms must be +12. Consequently, each palladium atom has a charge of +4. The correct name for pd3n4 is palladium(IV) nitride, where the Roman numeral IV indicates the +4 oxidation state of palladium.
