Chemistry for Kids: Naming Chemical Compounds.

In this lesson we will learn how to write and interpret chemical formulas for elements and compounds. Learning Outcomes. By the end of this lesson you will be able to: Write chemical symbols for elements. Write chemical formulas for compounds. Identify the number of each type of atom in a molecule based on its chemical formula.

Naming and Formula Writing Overview. Learning to name and write formulas for chemical compounds requires practice with immediate feedback to help you learn from mistakes. 1. Your first step is to learn how to tell what type of compound you have. This is something you need to master before naming or writing chemical formulas.To name a compound, the cation name and the anion named are added together. For example, NaF is also known as sodium fluoride. If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. The polyatomic ion name stays the same.Writing the chemical formula of compounds requires identifying chemical symbols, understanding numbers in formulas and recognizing key prefixes and suffixes. Prefixes like bi- and tri- help identify the number of ions in a molecule. Compounds such as stannous fluoride use non-standard terminology.

Molar Mass Calculator. Cations, Anions List.Scientists or chemists identify a particular chemical compound from its scientific name. But in general, they are known by their common name and many of them are a part of our day to day life. For instance, the chemical name of NaCl is Sodium chloride and its common name is salt.

How To Write The Names Of Chemical Compounds

The charges of cations and anions dictate their ratios in ionic compounds, so specifying the names of the ions provides sufficient information to determine chemical formulas. However, because covalent bonding allows for significant variation in the combination ratios of the atoms in a molecule, the names for molecular compounds must explicitly identify these ratios.

How To Write The Names Of Chemical Compounds

Write the second element Like the first element, that can be called a first name of the compound, the second element can be called the last name. The element name will end with the suffix ide for the covalent compounds. For example Dinitrogen hexafluoride.

How To Write The Names Of Chemical Compounds

Chemical symbols Each element is given its own chemical symbol, like H for hydrogen or O for oxygen. Every chemical symbol starts with a capital letter, with the second letter written in lower case.

How To Write The Names Of Chemical Compounds

By knowing the names of the elements and some basic rules, we can name some compounds to give the chemical formula. But. if we know the name of the compound, we can easily write the chemical formula. Write symbols for every element in the compound. If you find more than one atom of a particular element in the formula unit, You can write the.

How To Write The Names Of Chemical Compounds

When you name ionic compounds, you write the name of the metal first and then the nonmetal. Suppose that you want to name the compound that results from the reaction of lithium and sulfur. You first write the name of the metal, lithium, and then write the name of the nonmetal, adding an -ide ending so that sulfur becomes sulfide.

Naming and Writing Formulas for Chemical Compounds.

How To Write The Names Of Chemical Compounds

Before you can write your chemical formula, you need to write down the symbol of each atom present in your molecule or compound. You might be given a name of a compound, such as sodium chloride, and you must determine which atoms are present. Write Na for sodium and Cl for chloride, a form of the element chlorine, which combined create the.

How To Write The Names Of Chemical Compounds

Introduction. First off, decide if the compound is covalent or ionic.Remember that covalent bonding happens when all the elements in a molecule are non-metals (e.g. carbon dioxide, water, ammonia and methane) while ionic bonding happens between a metal and a non-metal (e.g. sodium chloride, magnesium oxide). If the compound is COVALENT, it’s all in the name.

How To Write The Names Of Chemical Compounds

Here is a look at the difference between different types of chemical names, including systematic names, common names, vernacular names and CAS numbers. Systematic or IUPAC Name The systematic name also called the IUPAC name is the preferred way to name a chemical because each systematic name identifies exactly one chemical.

How To Write The Names Of Chemical Compounds

A chemical nomenclature is a set of rules to generate systematic names for chemical compounds.The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC). The IUPAC's rules for naming organic and inorganic compounds are contained in two publications, known as the Blue Book and the Red Book, respectively.

How To Write The Names Of Chemical Compounds

Different instructors set out widely varying requirements for chemical nomenclature. The following are probably the most commonly expected: You should know the name and symbols of at least the first twenty elements, as well as all of the halogen and noble gas groups (groups 17-18). Name any binary molecule, using the standard prefixes for 1-10.

List of Chemical Compounds and their Common Names and.

How To Write The Names Of Chemical Compounds

Naming Ionic Compounds with Transition Metals. Write the name of transition metal as shown on the Periodic Table. Write the name and charge for the non-metal. If you have a polyatomic ion, use the Common Ion Table to find and write the formula and charge. Use the total charge on the non-metal (or polyatomic ion) find the charge on the.

How To Write The Names Of Chemical Compounds

Writing formulas for binary molecular compounds is like decoding a message. If you can name a compound from its formula, then it's easy to do the reverse. We will rely on some of the same rules.

How To Write The Names Of Chemical Compounds

The coordination compounds are named in the following way. (At the end of this tutorial we have some examples to show you how coordination compounds are named.) A. To name a coordination compound, no matter whether the complex ion is the cation or the anion, always name the cation before the anion. (This is just like naming an ionic compound.).

How To Write The Names Of Chemical Compounds

Bibliography: List of 131 compounds in the Solution Calculator database for which the density function is defined are for the Perry's Chemical Engineers' Handbook. D.W. Green, R.H. Perry, Perry's Chemical Engineers' Handbook, McGraw-Hill, (2) 99-118, 2008.
