Balancing Nuclear Reactions and Identifying Isotopes

This video tutorial explains how to balance nuclear equations through various examples. It covers the concepts of atomic and mass numbers, using isotopes like carbon-14, nitrogen-14, thorium-230, mercury-201, and uranium-238. The tutorial demonstrates balancing equations involving beta decay, neutron bombardment, alpha decay, electron capture, and carbon bombardment, emphasizing the importance of maintaining equal mass and nuclear charge on both sides of the equation.
