Exam 11: Nuclear Chemistry

A helium nucleus contains two protons and two neutrons.The mass of the helium nucleus is greater than the combined masses of two protons and two neutrons because binding energy has been added.

The process of electron capture can be considered as the

In the famous relationship: E = mc²,the symbol m represents

In positron emission tomography (PET),a positron collides with an electron and the two particles disappear in a burst of

decays by emission of an alpha particle.The product of this decay is

Which of the following isotopes produced in fission bomb explosions poses the greatest health risk to humans?

In nuclear fusion,

Nuclear power plants require fuel that has a higher percentage of Uranium-235 than needed for a bomb.

The bombardment of nitrogen-14 with alpha particles produces oxygen-17 and a proton.This process is called
