The systematic naming of binary compounds using the International Union of Pure and Applied Chemistry (IUPAC) conventions is fundamental in inorganic chemistry. It ensures clarity and universality in scientific communication by providing standardized names that precisely describe the composition and oxidation states of the compounds. Binary compounds consist of two elements, typically a metal (or metalloid) and a non-metal, and their correct nomenclature depends on identifying the cation and anion accurately, especially when transition metals are involved, which often possess multiple oxidation states.

Starting with the first compound, Barium chloride (BaCl2), barium, a Group 2 metal, forms a binary compound with chlorine. Since barium always exhibits a +2 oxidation state, the name is simply "barium chloride." Similarly, potassium sulfide (K2S) involves potassium, which has a fixed oxidation state of +1, and sulfur, which typically has a -2 oxidation state when forming sulfides, resulting in the name "potassium sulfide." Sodium fluoride (NaF) involves sodium (+1) and fluorine (-1), yielding "sodium fluoride."

Silver oxide (Ag2O) contains silver, a transition metal that often exhibits a +1 oxidation state, and oxygen (-2). Since silver is monovalent here, the common name "silver oxide" is acceptable; otherwise, the IUPAC name would be silver(I) oxide. Copper(I) bromide (CuBr) and Copper(II) bromide (CuBr2) demonstrate the necessity of Roman numerals to specify oxidation states. CuBr contains copper in +1 oxidation state, named "copper(I) bromide," while CuBr2 contains copper in +2 oxidation state, named "copper(II) bromide."

Iron(II) oxide (FeO) and Iron(III) oxide (Fe2O3) are distinguished by the Roman numerals indicating iron's oxidation states. Magnesium sulfide (MgS) involves magnesium (+2) and sulfur (-2), resulting in "magnesium sulfide." Aluminum oxide (Al2O3) reflects aluminum's +3 oxidation state and oxygen’s -2, classically named "aluminum oxide."

Calcium iodide (CaI2) features calcium (+2) and iodine (-1), resulting in the name "calcium iodide." The compound Ba3P2 contains barium and phosphorus, with barium in +2 oxidation state and phosphorus often in -3, thus the name "barium phosphide."

Mercury(I) iodide (Hg2I2) is a diatomic cation of mercury, and the name reflects the +1 oxidation state of mercury with the Roman numeral, becoming "mercury(I) iodide."

For sodium oxide (Na2O), sodium (+1) and oxygen (-2) form a standard binary ionic compound, named "sodium oxide." Beryllium sulfide (BeS) involves beryllium (+2) and sulfur (-2), named "beryllium sulfide."

Manganese(II) oxide (MnO) and Manganese(III) oxide (Mn2O3) highlight the multiple oxidation states of manganese, with the Roman numerals clarifying the specific oxidation state of manganese in each compound.

In all cases, the systematic nomenclature enhances precision, especially for transition metals where multiple oxidation states are common. Proper application of these naming conventions is vital for unambiguous chemical communication. The compound names provided here adhere to IUPAC standards, facilitating clear and accurate scientific dialogue internationally.
