In an ammonia molecule (NH3), nitrogen is the central atom. Nitrogen has four electron groups: Three N-H bonds and one lone electron pair. In a perfect tetrahedral structure, bond angles are 109.5 degrees. Would the bond angles between hydrogen molecules in ammonia be more, less, or equal to 109.5 degrees?

Listenbase your answer to the question on the information below.nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body.cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment.which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
