PPT-Ch. 15 and 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 Common Polyatomic Ions with a 1 charge. The ions are arranged in a lattice. There is attractive electrostatic forces between the ions which are very strong e.g. sodium chloride ionic lattices. . Give two properties of giant ionic structures. . 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:. Common Polyatomic Ions. Isotopes. Isotopes. : atoms of the same element that have different numbers of neutrons. Two isotopes of an element will have the same atomic number, but different mass numbers (and atomic masses). CARBON (above right). Polyatomic. Ions?. How do they form ionic compounds?. Section 6.3b 6.4b. Objective . 6.3b-4b. . I know the difference of a . polyatomic ion . vs. a . monatomic ion. I can write formulas and names of polyatomic ionic compounds. SNC2D. Polyatomic Ions. Polyatomic ions are groups of atoms that tend to stay together and carry an overall ionic charge. The ion is typically held together with covalent bonds. The polyatomic ion is capable of bonding with other ions. 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. 5 Charge ? Tripolyphosphate * means that they’re pretty common / important ones…learn these ? means Dusch has never used these but found them in a reference and though he’d include t Multivalent & Polyatomic Ions. Multivalent Metals. Multi = multiple. Valent. = charge. Metal = specifically transition metals. . List all of the possible . valencies. for the following metals:. Many ions are monoatomic BUT. Most ions are polyatomic (>1 atom). 330.07.01b.Names & Formulas - Polyatomic. There are . five common polyatomic. ions:. nitrate NO. 3. –. carbonate CO. 3. 2– . Bonding . is the joining of two atoms in a stable. arrangement.. There are two different kinds of bonding:. Elements will . gain. , . lose. , or . share . electrons to reach the electron configuration of the noble gas closest to them in the periodic table.. 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.
