16 g of a radioactive isotope are present at 2 :00 PM and 1 g remain at 2:00 PM the following day.If the radioactive isotope decay as an exponential model , what's the half-life in hours?

How do neutrons cause the release of energy from an atom, based on paragraph 7? The neutrons hit the atoms and split the energy, which makes more energy. The neutrons hit the atoms, which splits the atoms and releases their energy. The neutrons hit the atoms, which splits the atoms and releases uranium The uranium is used for energy. The neutrons hit the atoms and release more neutrons, which causes a chain reaction. Energy is generated from the chain reaction.
