Nuclear Reactions Emissions, Balancing, and predicting decays of Nuclear Reactions
Nuclear Chemistry • Many nuclei undergo spontaneous changes. These changes are usually accompanied by the emission of a particle from the nucleus. The process is called Radioactive Decay. Consider Mass Number = # protons + # neutrons Atomic Number = # protons Mass Number 40 Nuclear symbol K K Atomic Number 19
Undergoes Radioactive Decay 0 40 Ca e 20 -1 Nuclear Chemistry • Many nuclei undergo spontaneous changes. These changes are usually accompanied by the emission of a particle from the nucleus. The process is called Radioactive Decay. Consider 40 Balanced Nuclear Equation Nuclear symbol K + 19 Superscripts and subscripts are equal on both sides of the equation
