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???

1)SO2, the sulfur, when it burns in air reacts with the O to form SO2. When Mg burns in air it reacts with the O and the N in the air and forms both MgO and Mg3O2. The product SO2 is a gas and MgO and Mg3O2 is a solid.
2)It is ionic. Ionic bonds form between a + ion and a - ion. Na is + and F is -.
3)P with O is covalent. Both elements are negative ions so they share. You need a + and a - to be ionic.
4)No! Lots and lots of liquids. Some solids also.
5)O and S are in the same groups because they both have 2 electrons in their outer shells. P and S are next to each other because they both have the same number of energy levels (3).
Get an "A".

1. MgO is a white powder. SO2 is an acrid gas.
2. When NaF forms it is definitely ionic because F is the most reactive nonmetal and takes the electron.
3. P forms several oxides. One is P2O5,(here it takes a +5 charge), and is ionic
4. Covalent bonds are made with carbon and hydrogen, as well as in diatomic molecules
5. S and O are in the ame group because they both have 6 electrons in he outer ring. P and S are beside each otherbecause S has one more proton and electron than P
