Ionic Compounds • Ionic formulas are based on the ions of the atoms involved Example: What is the name of Ca 3 N 2 ? Ca is the positive ion and is calcium. N is the negative ion and is nitrogen. Drop the ending of the negative ion, ...
Chemical Formulas: Both ionic and molecular compounds can be represented with chemical formulas. The chemical formulas must include the chemical symbol and number of atoms of each element present. The empirical formulas of ionic compounds are always equal to their molecular formulas. ...

Chemical formulas may be used in chemical equations to describe chemical reactions. For ionic compounds and other non-molecular substances empirical formula may be used, in which the subscripts indicate the ratio of the elements. The 19th-century Swedish chemist J枚ns Jakob Berzelius worked out ...
Chemical formulas of Ir(III) complexes examined Full size image In this work, we present a series of iridium(III) complexes with three cyclometalating ligands based on bzq. We report herein an extensive theoretical investigation of the structural, electrochemical, and photophysical properties of the...
As an aid for determining subscripts in formulas for ionic compounds, the positive and negative charges can be "crossed over." Crossing over is a method of balancing the charges between ions in an ionic compound. For example, the formula for the compound formed by the aluminum ion, Al3+...
In many cases, two elements can combine in a variety of ways to form entirely different compounds. (With the exception of metals that can form more than one charge, this cannot happen with ionic compounds.) Carbon, for example, can share electrons with one oxygen to form CO (carbon monoxid...
Chemical Nomenclature and Formulas for Ionic Compounds Ionic Compounds Consist of cations (positive ions) and anions (negative ions) Usually composed of metals (cations) and nonmetals (anions) Oxidation numbers (charges of ions) are important Types of Ions Monatomic ions: Consist of a single atom...
