NAME (first and last) CHEM______ SECTION ______ 3. From the information given in lecture, complete the following table. Compound Name

Molecular Formula

sulfur difluoride PCl3 silicon dioxide H2S carbon tetraiodide SiBr2 P4O10 4. Polyatomic ions are a group of atoms that are held together by covalent interactions, and the entire group of atoms carries the charge. The most common polyatomic ions contain oxygen. Their names may not seem to make sense now, but there is a system to this madness. Background info Ion

i) What element is associated with the prefix “nitr-”?

ii) Does the suffix of each name depend on the charge of the ion?

iii) Does the suffix tell you how many oxygen atoms there are?

iv) Compare nitrate to nitrite. Which ion has more oxygen atoms?

v) Compare sulfate to sulfite. Which ion has more oxygen atoms? 5. Consider the two oxy- ions of chlorine, ClO2− and ClO3−. Which ion would have the –ate ending?
