1. Natural Transmutations Do Now: what is a transmutation?

2. Transmutation
2 types
Natural
Artificial

3. Natural Transmutation
Happens all by itself (spontaneous)
Not affected by anything in environment
1 term on reactant side
Original isotope
2 terms on product side
Emitted Particle
New Isotope

4. Natural Transmutation
16N  0e O 7 -1 8
2 terms on product side
1 term on reactant side

5. Balancing Nuclear Equations
16N  0e O -1 7 8
Conservation of mass number: 16 =
Conservation of atomic number: 7 =

6. so Y = 228 232 = 4 + Y Conservation of Mass Number:
232Th  4He X Y Z 90 2
Conservation of Mass Number:
sum of mass numbers on left side must = sum of mass numbers on right side

7. so Z = 88 90 = 2 + Z Conservation of Atomic Number:
232Th  4He + 228X Z 90 2
90 = Z
so Z = 88
Conservation of Atomic Number:
sum of atomic numbers on left side must = sum of atomic numbers on right side
