1. When sulfur burns, it reacts w/ Oxygen in the air to form an oxide of sulfur (SO2). Compare the Physical properties of SO2 with the oxide of MgO (produced when Mg is burned).

2. If Na is reacted with Fluorine, would you expect it to be ionic or covalent and why?

3. When P is reacted with O, is it ionic or covalent?

4. Is it true that covalents are only produced from 2 gases?

5. Explain why oxygen and sulfur are in the same group and why are Phosphorous and sulfur next to eachother going across the period???

I'm stuck with this one. I know that C will triple bond to O and each will have two valence electrons left. Does it have a linear electronic geometry or a tetrahedral electron geometry? Please help!
