An isotope of rutherfordium (mass # 257, atomic # 104), is formed by the bombardment of californium-249 by carbon-12. in the process, neutrons are emitted. the new isotope formed decays rapidly, emitting an alpha particle.
a) how many neutrons are emitted for ever cf-249 bombarded?
b) write the nuclear symbol for the isotope formed by the decay of rf-257.

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. type your answer here. (score for question 4: of 5 points) make a general statement about the reactivity of the metals in this experiment. type your answer here.
