![]() Some elements are very unstable (reactive) if they are moving around as a single atom. "Diatomic" means it contains two atoms of the same element ("di" means two). Use chemical test strips to help identify various ions and determine their concentration. Use a flame color test to help identify certain metal ions.Ĩ. Use the color of a salt to help identify certain metal ions.ħ. Learn names and formula of ternary compounds (compounds with 3 different elements).Ħ. Learn names, formulas, and correct charges of polyatomic ions. (Examples: CO 2-carbon dioxide, SO 3-sulfur trioxide, CCl 4-carbon tetrachloride).Ĥ. These are non-metals that have bonded with other non-metals by sharing their electrons (covalent bonding). Binary Compounds with covalent bonding: Write names and formulas for binary compounds that use covalent bonding. (Examples: NaCl-sodium chloride, CaBr-calcium bromide, FeCl 3-Iron(III) chloride).ģb. These are positive metal ions that have bonded with negative non-metal ions. Binary Compounds with ionic bonding: Write names and formulas of binary compounds that use ionic bonding. Binary Compounds (compounds made from 2 different elements)ģa. Learn the correct charges of monatomic ions. Organic compounds, as your remember, are based on carbon and chains of carbon which are normally just bonded to other non-metal elements like hydrogen, oxygen, and chlorine.ġ. Inorganic compounds are also non-metals bonded with non-metals. The are often called "salts" or "metallic salts". Inorganic compounds often contain metals bonded with non-metals. In this lab, you will be doing both qualitative and quantitative analysis of inorganic compounds. Quantitative analysis is the analysis that comes up with how much is present. "Qualitative" means you are saying if the substance is present, but you aren't saying how much is present. Qualitative Inorganic Analysis is the identification of certain inorganic ions (both positive and negative). So this lab also has some hands-on activities to investigate some of the chemicals that you are learning to name. Learning nomenclature is mostly a mental exercise. Also, this lab will test your knowledge of nomenclature. In other words, there will be a minimum of instructions on nomenclature in this lab except for giving you many examples to use as a pattern. These have the bulk of the information you need to learn chemical nomenclature. You ought to do those before you do this lab. Here is a link to a menu page to tutorials on nomenclature. It takes practice and study, but the reward is that it gives you the ability to talk to people you couldn't talk to before. ![]() Understanding chemistry nomenclature is like learning any language. In chemistry, "nomenclature" is learning to call out chemical names. When students get their diploma, the nomenclator is the person who calls out the students' names. " Nomen" means names and "clator" is a person who calls out. The word Nomenclature comes from Nomenclator, who is a person who calls out names. Lab 6: Nomenclature and Inorganic Analysis
