- Explanation: It is a beta
Explanation: The process of combining two nuclei together to form a single nucleus is called fusion. For example, our sun takes 2 hydrogen atoms, and using a tremendous amount of heat, combines them into a single helium atom. This also produces the energy of the sun. 23) Which process is the primary source for energy used by living organisms on Earth?
Explanation: The correct answer is A. Fusion is the main process that occurs in the core of stars, including our sun. 24) In the mid 1930s Enrico Fermi bombarded uranium with thermal neutrons and observed the release of a large amount of energy. This happened because the heavy uranium nucleus split into two lighter nuclei, releasing two or three neutrons along with a large amount of energy. What is this process called?
Explanation: Nuclear fission means to smash or split the atom. This process can continue in a controlled manner to produce nuclear energy in a nuclear power plant. In an uncontrolled setting, the entire material undergoes fission releasing a huge quantity of heat energy and causing a violent explosion. 25) 
Iodine-131 is a radioactive isotope that is used as a medical tracer to study and treat the thyroid gland. This radioactive element emits both beta particles and gamma waves. To effectively stop both beta particles and gamma waves, scientists use a chamber composed of
Explanation: To stop both emissions, the chamber should be made of lead. Notice the illustration. Only lead will stop gamma waves, although copper will stop beta particle penetration. 26) This radioactive particle, emitted from carbon-14, has a negative charge. It contains sufficient energy to burn human skin and can pass through paper. It is a(n) ___________ particle.
Explanation: It is a beta particle. Beta particles can be stopped by either a thin copper or lead sheet. Gamma waves are electromagnetic waves; they are not considered to be particles.
