Identify the true statement s about the molecular orbital theory The molecular orbital theory describes molecules with delocalized bonding The molecular orbital theory describes the bonding in molecules in terms of a single electron configuration The molecular orbital theory requires two or more resonance formulas to describe the bonding in molecules

What is the environmental impact of using radioactive tracers in medicine to help diagnose disease The radioactive isotope must be stored in special containers and allowed to decay before being disposed The value of this tool to society is not high enough to warrant the cost of production storage and disposal The tracer contains harmful radioactive isotopes that must be disposed of safely to prevent soil and water contamination The radioactive isotope poses little threat to wildlife but is harmful if it gets into human drinking water and crop soil
