What is the valence electron configuration of Group 6A elements? What are some property differences between oxygen and polonium?
Answer to relevant QuestionsWhat are the Lewis structures for the two allotropic forms of oxygen? How can the paramagnetism of O2 be explained using the molecular orbital model? What are the molecular structure and the bond angles in ozone? In large doses, selenium is toxic. However, in moderate intake, selenium is a physiologically important element. How is selenium physiologically important? What is a disproportionation reaction? Use the following reduction potentials ClO3- + 3H+ + 2e- → HClO2 + H2O ϐo = 1.21 V HClO2 + 2H+ + 2e- → HClO + H2O ϐo = 1.65 V To predict whether HClO2 will disproportionate. What are the two most abundant elements by mass in the earth’s crust, oceans, and atmosphere? Does this make sense? Why? What are the four most abundant elements by mass in the human body? Does this make sense? Why? It takes 15 kWh (kilowatt-hours) of electrical energy to produce 1.0 kg of aluminum metal from aluminum oxide by the Hall–Heroult process. Compare this to the amount of energy necessary to melt 1.0 kg of aluminum metal. ...
