1 Tuesday Bellwork Match the following ions with their names.
___NO3- A. nitride ___CN- B. silver ion ___Ag+ C. cyanide ___NH4+ D. ammonium ___N3- E. chloride ___Cl- F. nitrate

2 Wednesday Bellwork Practice this Friday ion quiz along with polys:
NO _______________________ Mercury (II) _______________________ Ag+ _______________________ CN- _______________________ Potassium _______________________ Bromide _______________________ Ba2+ _______________________

3 Unit 6 Ch 9 Notes Part 4 Putting it together and the Laws

4 9.5 Distinguish Between the two types of compounds!
Molecular Ionic Two or more nonmetals Low melting point Low boiling point Example CO2 Metal and nonmetals High melting point High boiling point Solid at room temperature Electrically neutral Example NaCl

5 Which of the following is molecular and which is ionic, so how do you name it?
NaBr CO2 O3 NO KCl AlBr3 Ionic Molecular Molecular Molecular Ionic Ionic

6 AgNO3 PCl3 Ba3N2 Hg2I2 SiO2 SO3

7 Molecular formula- chemical formula written for a molecule
Chemical formula- shows the number and kinds of atoms in the smallest representative unit of the substance. Molecular formula- chemical formula written for a molecule Ex. CO2 O2 or H2O2 The formula for this compound would be C5H12O

8 Formula unit- chemical formula written for an ionic compound
Formula unit- chemical formula written for an ionic compound. -lowest whole-number ratio of ions in the compound

9 Law of Definite Proportions- In all samples of any chemical compound, the elements are always combined in the same proportion by mass. Ex. Water is always 88.9%O and 11.1%H by mass

10 Law of Multiple Proportions- Whenever two elements form more than one compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers.

11 Formula Naming: A Summary

12 Thursday Bellwork Name the following compounds.
