- Miller and Urey created a reaction chamber that simulated conditions in Earths early atmosphere to test the hypothesis that______. a. lightning-fueled atmospheric reactions could have produced organic compounds b. meteorites contain organic compounds c. organic compounds form at hydrothermal vents d. oxygen prevents formation of organic compoundsarrow_forwardA. The first shell corresponds to the first energy level, and it can hold up to 2 electrons. Hydrogen has one proton, so it has 1 electron and one vacancy. A helium atom has 2 protons, 2 electrons, and no vacancies. B. The second shell corresponds to the second energy level, and it can hold up to 8 electrons. Carbon has 6 electrons, so its first shell is full. Its second shell has 4 electrons and four vacancies. Oxygen has 8 electrons and two vacancies. Neon has 10 electrons and no vacancies. C. The third shell corresponds to the third energy level, and it can hold up to 8 electrons. A sodium atom has 11 electrons, so its first two shells are full; the third shell has one electron. Thus, sodium has seven vacancies. Chlorine has 17 electrons and one vacancy. Argon has 18 electrons and no vacancies. Figure It Out: Which of these models have unpaired electrons in their outer shell?arrow_forwardAlchemists were the forerunners of modern-day chemists.
