Iodine would be a poor conductor of electricity. I2 is composed of covalent bonds and is a brittle solid at room temperature.
Even though Oxygen is also composed of covalent bonds is has a π bond, so it has extra mobility of electronic current that Iodine - Both would be poor conductors, however.
Oxygen would only be a significant conductor in the liquid phase.

Oxygen and Iodine are both poor conductors of electricity but Oxygen is a gas at room temperature and Iodine is a solid so my guess is Iodine.
Rational: Zinc is a metal which are generally good conductors. Oxygen and Iodine are both non-metals and have no electorons that are easily freed to conduct electricity.
Oxygen being a lighter element is a gas at room temperature. Iodine is quite heavy so one would expect it to be a solid even though it is a Halogen (Halogen's are reactive and tend to be gases if they have a low number on the periodic table). The element immediately above it on the periodic table, Bromine, and the element to the left of it on the periodic table, Tellerium, are both solids, so it would be no surprize that Iodine would be too. As a nonmetal, Iodine would be expected to be brittle.
(In fact, Iodine is a brittle solid at room temperature and is a poor conductor)

IODINE.
Oxygen is a gas at room temperature.
Zinc is a solid at room temp., but it is metallic so will conduct electricity, because each zinc atom is held in a lattice surrounded by a 'sea of electrons'. The electrons in this 'sea' are free to move so electricity will conduct.
Iodine is a solid at room temperature. However, individual iodine molecules are two iodine atoms covalently bonded together. There are no de-localised electrons so it will not conduct electricity.

well zinc is a metal so will conduct electricty very well as all metals do and oxygen is a gas at room temp, would be very difficult to breathe in if it was a brittle solid.

you initiate via look on the climate with only one oxidation selection. Potassium is a collection a million factor so a million+. Magnesium is a collection 2 factor so 2+. aluminum is 3+. Nitrogen could be 3+, 3-, or 5+. Selenium could be 4+, 6+, 2-. So in case you look on the oxidation numbers you have left nitrogen has to 3- and selenium must be 2-.
