PPT-Polyatomic Ions

Many ions are monoatomic BUT Most ions are polyatomic gt1 atom 3300701bNames amp Formulas Polyatomic There are five common polyatomic ions nitrate NO 3 carbonate CO 3 2 . Names of Common Polyatomic Ions. . Ion Name Ion Name. . NH. 4. . +. ammonium. . CO. 3 . 2-. carbonate. *NO. 2. . -. *nitrite . HCO. 3. . -. and stuff like that.. A complex ion is the exception to a rule.... It is an ionic compound that has an overall charge.. Complex ions are identified using square brackets. [ ]. Complex Ions. Are soluble.. 6 Polyatomic Ions. Polyatomic Ions . Tightly bound groups of atoms that behave as a unit and carry a charge.. Ammonium . NH. 4. +. Cyanide. CN. -. Sulfite . SO. 3. 2-. Examples:.

Has an overall ionic charge.. Some. polyatomic ions exist in families:. Parent ion. (-“ate” ending). Derivatives. (related to parent). obtained by:. adding a hydrogen atom, OR. adding/removing oxygen atoms. Type 1: When hydrogen is added. Nomenclature Warm-up #6. . Identify these compounds as ionic or covalent, then name them. Remember to use Roman numerals when necessary!. ____ (I or C) 1. V. 3. As. 2. ____ (I or C) 2. Hg. 3. P. ____ (I or C) 3. . Multivalent & Polyatomic Ions. Multivalent Metals. Multi = multiple. Valent. = charge. Metal = specifically transition metals. . List all of the possible . valencies. for the following metals:. How elements become charged. How elements become charged. ION – A charged atom. All elements on the periodic table are NEUTRAL because they have the same number of . protons (+) and electrons (-). “Observation of a discrete time crystal,” . J. Zhang, P.W. Hess, A. . Kyprianidis. , P. Becker, A. Lee, J. Smith, G. Pagano, I.D. . Potirniche. , A.C. Potter, A. . Vishwanath. , N.Y. Yao, . and.  C. . Simple Ionic Compounds. Concept:. Ionic Formulas are formed from positive and negative ions.. Fact 1:. Positive ions are formed by metals that lost electrons.. Examples: Na. 1+. Mg. 2+. A. 3+. MACROSCOPIC SCALE. Elements combine to make compounds.. ATOMIC SCALE. Atoms combine to make molecules, or extended structures.. What we’ll cover…. Compound Formulas. Ions. Monatomic. Polyatomic. Ionic Compounds. INORGANIC Nomenclature Nomenclature - Humor “Ferrous Wheel” Fe = iron (Latin = ferrum) Fe 2+ = lower oxidation state = ferr ous Fe 3+ = higher oxidation state = ferr ic BaNa 2 “ BaNaNa Oxyanions. Oxyanions- negative ions containing oxygen.. These have the suffix “-ate” or “-ite”. “-ate” means it has more oxygen atoms bonded, “-ite” has less. For example. SO. 4. 2-. sulfate. HOMEWORK. Do all . odd exercises . in this book on a separate sheet of paper.. DO NOT WRITE IN THE BOOK.. Chapter 1. Symbols and Nomenclature of the elements. There is interesting info where the elements got their name, but nothing we will cover..
