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.
