A uranium 238 nucleus, initially at rest emits n alpha particle with a speed of 1.4×107ms. Calculate the recoil speed of the residual nucleus thorium 234. Assume that the mass of a nucleus is proportional to the mass number. View Solution Write the complete symbol a. The nucleus with ato...
This process changes the nuclear composition of the nucleus of an atom through an emission of particles. The type of radiaoctive decay typically depends on the particles that are converted and emitted after the reaction. Some of the common radioactive decays includ...
It was the first fissile Uranium isotope to be discovered. When one neutron from the U-235 fission reaction causes another nucleus of this metal to undergo fission, it causes the entire chain reaction to continue. This condition is called the “critical condition” while the mass of U-235 re...

The nucleus of an atom does not have distinct boundaries but is assumed to be in a spherical shape. Thus, the volume of the nucleus can be determined to obtain its density. The density of the nucleus varies with distance from the center of the nucleus, becoming...

Figure 1.3 (b)shows that if the nucleus of a heavy element is split into two nuclei of medium atomic numbers each nucleon will have less mass than previously and the equivalent amount of energy will be spontaneously released. To illustrate this assume for simplicity that uranium 236 divides int...
The nucleus of atoms was discovered by Ernest Rutherford in the early 1900s through his gold foil experiments. In the experiment, he found that positively charged particles were sometimes encountering a positively charged region of atoms and being deflected by it. This evidence ...
What element with a mass number of 100 has 56 neutrons in its nucleus? What is the mass number of oxygen? What is the mass number of magnesium? What is the mass number of the isotope lithium-7? What is the mass number of hydrogen? What is the mass number of the uranium-238 atom...
