A binary ionic compound is known to contain a cation with 51 protons and 48 electrons. The anion contains one-third the number of protons as the cation. The number of electrons in the anion is equal to the number of protons plus $1 .$ What is the formula of this compound? What is the name of this compound?

Key Concepts

Atomic Structure and Ion Formation

This concept involves the understanding that atoms are made up of protons, neutrons, and electrons, and that an imbalance between the number of protons and electrons results in a charged species known as an ion. When an atom loses electrons, it becomes a positively charged cation, and when it gains electrons, it becomes a negatively charged anion.

Periodic Table and Element Identification

The periodic table arranges elements by increasing atomic number, which is the number of protons in the nucleus. Identifying an element based on its atomic number allows one to determine the chemical identity of the ion formed, as well as predict likely ion charges based on its electron configuration and common oxidation states.

Ionic Compound Formation and Charge Neutrality

Ionic compounds are formed when cations and anions combine in ratios that balance their charges to yield a neutral compound. This principle of charge neutrality is used to derive the empirical formula of an ionic compound by ensuring that the total positive charge equals the total negative charge.

Chemical Nomenclature for Ionic Compounds

The naming of ionic compounds follows systematic rules where the cation is named first followed by the anion. For cations that can exhibit multiple oxidation states, a Roman numeral is used to indicate its oxidation state, while the anion takes on an '-ide' ending. This convention helps in clearly identifying the composition and charge of the ions in the compound.
