An element has a atomic number of 65 and a mass number of 132. This element undergoes  K-Electron capture. The mass number of the element formed is:

Enter a balanced nuclear equation for the production of iodine-131, used in treatment of some cancers, from the beta decay of tellurium-131. Express answer as a nuclear equation.

a) Mrs. Price's son, Liam is currently working as a boilermaker at the Darlington Nuclear Power plant. He is working with Uranium-237 which has a half-life of 13.75 days. What mass of an initial sample of 567.5g of uranium-237 would remain after 56 days? b) Write the complete reaction for the decay of Po-210 if it undergoes 2 consecutive alpha decay followed by a beta decay followed by another alpha decay.

The difference between the calculated and experimentally measured masses of an atom is called binding energy per nucleus average mass mass defect binding energy per mole

Radium is a radioactive element whose nucleus emits an alpha particle
