Chapter 7 and Acid Review Ironic isn’t it What’s in a name ironically Molecular Stuff Acidic Overload Mixed Bag Bagging it

Ironic isn’t it State the Law of Conservation of Matter. –During a chemical reaction matter is neither created or destroyed therefore the mass of the reactants must equal the mass of the products

Ironic isn’t it Discuss what elements are involved in an Ionic Bond and what happens to the electrons. –Metal (+) to a non-metal(-). The electrons are taken from the metal by the non-metal because it is much more electronegative (able to attract and hold electrons)

Ironic isn’t it Name at least 3 properties of Ionic Compounds –Strong attraction between ions therefor solid at room temperature, High melting and boiling points, brittle….

Ironic isn’t it Discuss the difference between a Binary I and Binary II Compound –Binary I compound- the metal comes from the s block plus Ag, Zn and Al. These metals can only have one possible + charge –Binary II compound- these metals come from the d and lower p blocks, the metal can have more than one + charge.

Ironic isn’t it How do you name a Binary I and Binary II compound? –Binary one – (+) ion keeps its name, (-) monoatomic ion ends in ide. Polyatomics keep their name –Binary II – roman numerals indicate the (+) ion’s charge, (-) monoatomic ion ends in ide. Polyatomics keep their name
