Determine number of neutrons in an isotope
Web20 hours ago · The radioactive isotope forms continuously in the upper atmosphere as cosmic rays—high-energy particles from space—collide with gas molecules, spawning neutrons. When one of these neutrons knocks out a proton in a nitrogen atom, that nitrogen is transformed into 14 C. As it inhaled CO 2, the cedar had incorporated the 14 … WebStep 3: Calculate the number of neutrons by subtracting the atomic number (the number of protons) from the mass number. Using the results from steps 1 and 2, we can find the …
