Chapter 10 & 7A . Ions Monatomic Ions Ion Formulas and Names. Ion Vocabulary. An ion is an atom or group of atoms that have a charge. A cation is a positive ion. An anion is a negative ion. 11 protons 11 electrons. 11 protons 10 electrons. Na +. Na. 17 protons 18 electrons.

Unit 6 – Redox Reactions and Electrochemistry. Redox reactions involve a transfer of electron density from one atom to another. Two common examples include the formation of salt and the formation of water:. 2 Na + Cl 2  2 NaCl & 2H 2 + O 2  2H 2 O .

Writing Formulas and Naming Compounds. SC Standards. PS-4.5 Predict the ratio by which the representative elements combine to form binary ionic compounds, and represent that ratio in a chemical formula. “Perhaps one of you gentlemen would mind telling me just

Chemical Reactions. Chemical Reactions. Chemical Reactions happen when atoms join together in a process called Chemical Bonding. Chemical Bonding happens in the outer energy levels of the reacting atoms. Definitions.

Oxidation States. Review: Redox reactions involve one substance being oxidised and another reduced. What is oxidation? What is reduction?. Review:. Oxidation always involves loss of e-; it can also involve the gain of oxygen and/or loss of hydrogen

Oxidation Numbers:. In order to recognize which reactant is oxidized and which is reduced it is important to be able to follow the movement of the electrons.

Redox Net Ionics. Oxidation number on at least two elements must change. Types of Redox RXNS. RXNs: Single replacement, synthesis, and some decomposition. To predict products look at the reactants to see if there are oxidizing and reducing agents.
