Names and formulas for ionic compounds worksheet answers

Nomenclaturea collection of rules for naming things, is important in science and in many other situations. The simplest of these are binary compoundsthose containing only two elements, but we will also consider how to name ionic compounds containing polyatomic ions, and one specific, very important class of compounds known as acids subsequent chapters in this text will focus on these compounds in great detail. We will limit our attention here to inorganic compounds, compounds that are composed principally of elements other than carbon, and will follow the nomenclature guidelines proposed by IUPAC, names and formulas for ionic compounds worksheet answers. The rules for organic compounds, in which carbon is the principle element, will be treated in a later chapter on organic chemistry.

This is a worksheet that provides students with a bit more practice naming and writing formulas for ionic compounds. It includes a variety of common polyatomic ions like nitrate, sulfate, and carbonate, as well as less common ions like chromate, oxalate, perchlorate, and bisulfate. It also contains a variety of monovalent cations, like sodium, potassium, barium, and aluminum and multivalent cations, such as copper II , nickel II , titanium III and gold V. This worksheet includes some simple instruction on how to write the formula for ionic compounds and a brief explanation of the criss-cross technique. There are 23 compounds that require cation symbols, anion symbols, compound formulas, and compound names.

Compounds of these metals with nonmetals are named with the same method as compounds in the first category, except the charge of the metal ion is specified by a Roman numeral in parentheses after the name of the metal. Or add the next worksheet to the back to save paper. These worksheets are a great way to enhance your instruction, to offer practice problems in class, or to do as homework. Grade Levels. Ionic Compounds To name an inorganic compound, we need to consider the answers to several questions. Out-of-date nomenclature used the suffixes — ic and — ous to designate metals with higher and lower charges, respectively: Iron III chloride, FeCl 3 , was previously called ferric chloride, and iron II chloride, FeCl 2 , was known as ferrous chloride. For example, you may see the words stannous fluoride on a tube of toothpaste. Formats Included. Professional development. Ca 3 P 2 , calcium phosphide. Elementary ELA. Middle school.

Compounds Containing Only Monatomic Ions The name of a binary compound containing monatomic ions consists of the name of the cation the name of the metal followed by the name of the anion the name of the nonmetallic element with its ending replaced by the suffix — ide. Fun educational games for kids. High school math. Ca 3 P 2 , calcium phosphide. PreK science. Molecular compounds can form compounds with different ratios of their elements, so prefixes are used to specify the numbers of atoms of each element in a molecule of the compound. Special education. High school science. Other specialty. Music composition. Comprehensive K personalized learning. This lesson is super easy to implement! This assignment contains instruction for those who may have been absent for the lesson. From the answers we derive, we place the compound in an appropriate category and then name it accordingly.
