Presentation transcript:

1) The number of neutrons in 17O is:

2) What is produced when 83Sr emits an alpha particle?

3) For a nucleus that undergoes alpha decay, what is the disintegration energy if the mass of the alpha particle, daughter and parent are A, B, and C, respectively. (A+B+C)/c2 (A+B+C) * c2 (A+B-C)/c2 (A+C-B)/c2 (C-A-B) * c2

4) When a gamma ray is emitted from the excited state of 12C, the resulting nucleus is:

5) When a neutron strikes an unknown nucleus, the observed products are 28Si and 2H. What is the unknown nucleus?

6) For a typical fission reaction represented by: n + 235U ---> X ---> N1 + N2 + neutron(s), the value of X is?

7) Singly charged Uranium ions are sent through a mass spectrometer with an accelerating voltage of 1002 volts and a magnetic field strength of .3530 T. If the radius of curvature of the resulting path in the B-field is measured to be 20.00 cm, find the mass (in kg) for one U ion

8) Estimate the energy released when one Uranium atom undergoes nuclear fission. Assume that that a 235U nucleus has just absorbed a neutron and split into two positive fission fragments that are very close together - about 10-14 m apart. They now fly apart due to the repulsive coulomb force. Find their total kinetic energy when they are very far from each other. Assume that the atomic numbers of the fission fragments are Z = 39 and Z = 53.

9) Now find the energy released when one kilogram of Uranium undergoes fission. You will need to know the number of atoms in a kilogram of Uranium.

Define alpha, beta, gamma decay Write sample equations for each including 3 equations for beta decay (+,-,electron capture) Mass defect and binding energy Half life and radioactive decay
