List three types of radioactive decay. For each type, describe how the atomic number and the atomic mass change.
 
  What will be an ideal response?

Strong pressure gradients are associated with uniformly cold temperatures.
 
  Indicate whether the statement is true or false

Answer to Question 1

a. Alpha decay (2 protons and 2 neutrons) means an alpha particle is emitted from the nucleus, resulting in the mass number being reduced by 4 and the atomic number being decreased by 2.
b. Beta decay (an electron) is given off from a nucleus, the mass number remains unchanged; however, because the electron has come from a neutron, the nucleus contains 1 more proton than before. Therefore, the atomic number increases by 1.
c. Electron capture by the nucleus results in a proton converting to a neutron. In this scenario, the mass number remains unchanged, and the atomic number decreases by 1.

Answer to Question 2

FALSE
