How can a scientist assess whether a pure niobium (Nb) sample is responsible for contaminating the lab with radioactivity?
What type of particle has no mass or charge?
What is the most penetrating kind of radiation product that can be shielded with aluminum foil?
While a certain isotope decays, it emits photons. What kind of decay is happening?
A scientist notices that a lump of niobium is warm to the touch and wonders if nuclear reactions are taking place in the metal. How can she find out?
Which can have either a positive charge or a negative charge when they are released during radioactive decay?

An atom that has 84 protons and 86 neutrons undergoes a reaction. At the end of the reaction, it has 82 protons and 84 neutrons. What happened to the atom?
An isotope undergoes radioactive decay. The new isotope that forms has an atomic number that is 2 less than the original isotope’s. Which kind of decay has occurred, and how do you know?
