Chemistry In Context
- What are similar and different about the Lewis structure ?arrow_forwardBased on the Lewis structures for hydrogen and helium, explain why buoyant balloons are filled with helium instead of hydrogen gas, even though hydrogen gas is cheaper and more buoyant. HHe:: a. Helium's duet makes it stable and inert (unreactive). b. Helium's duet makes it unstable and chemically reactive. c. Helium has one more electron than hydrogen, which helps add color to the balloon.arrow_forwardWhat is the geometric structure of the boron trifluoride moleCule, BF3?
