Understanding Chemical Nomenclature: Naming Ionic, Covalent, and Acids

This guide provides a comprehensive overview of chemical nomenclature, focusing on the naming conventions for binary ionic compounds, binary covalent compounds, ternary ionic compounds, and various types of acids. Learn the steps for identifying cations and anions, handling multivalence metals, and using prefixes for covalent compounds. Master the rules for naming acids based on their structure. This resource is essential for students and anyone looking to deepen their understanding of chemical naming principles.

Presentation Transcript

  1. Chemical Nomenclature *Binary Ionic Compounds *Binary Covalent Compounds *Ternary Ionic Compounds *Acids

  2. Types of Compounds • Type A Binary Ionic – Contains a single-valence metal (cation) and a non-metal (anion) • Type B Binary Ionic – Contains a MULTIvalent metal (cation) and a non-metal (anion) • Binary Covalent (Molecular) Contains two non-metals. (There are exceptions to this rule!)

  3. Binary Ionic Compounds (Type A – no multivalence metals) • Step 1 – Make sure the first element is a metal that is NOT multivalent • Step 2 – Write the name of the cation (this is the metal) first. • Step 3 – Write the name of the anion using the –ide ending.

  4. Naming Ionic CompoundsType B – with multivalence metals • Step 1 – Identify the metal and check the multivalence list. (If it isn’t there, name it as a Type A binary ionic compound.) • Step 2 – Identify the ANION and determine the charge. • Step 3 – use algebra to determine the charge on the cation. • Step 4 – Name the cation followed by a roman numeral that MATCHES its charge. • Step 5 – Name the anion using the –ide ending.

  5. Naming Binary Covalent Compounds • Identify the first element. If there are two or more atoms use the prefix to match the number of atoms. • Identify the second element and use a prefix to indicate the number of atoms present. • Write the name of the compound using the –ide ending.

  6. Ternary Ionic Compounds Type A and Type B • Step 1: Identify the cation and determine if you need to use Type A or Type B naming procedures to name it. • Step 2: Write the name of the cation. • Step 3: Write the name of the anion. • Step 4: Rejoice, for you are finished!

  7. Naming Acids • Determine if it is a BINARY acid or a TERNARY acid. • If it is BINARY acid, change the name of the element the hydrogen is with, change the ending to –ic, and put hydro- in front. • Example: HCl • Chlorine becomes chloricand put hydro in front…. Hydrochloric Add the word ‘acid” HCl = “Hydrochloric acid”
