All Questions must be 2-5 Sentences, and include correct capitalization or punctuation.

Question

• All set up and steps of work must be shown
• Answer MUST INCLUDE correct sig figs and correct units
• All MOLAR MASSES MUST be calculated with NO rounding from the periodic table.
_____

Question 1- Explain the different processes that occur during fusion and fission reactions.

Question 2- Name two isotopes involved in fusion reactions.

Question 3 & 4A and 4B are combined.
234. 234
235. X → 91 y+Z

Question 3: Identify X, Y and Z. Must use simple math to show work and explain how many protons, neutrons, and electrons each of the products and reactants have to demonstrate that both sides of the reaction meet the requirement of conservation of mass. (class notes have example problems)
Question 4A: Explain what type of nuclear reaction has occurred and what particle is emitted.
Question 4B: Has transmutation occurred?

Answer 1

Question 1: In fusion reactions, two smaller atomic nuclei combine to form a larger nucleus, releasing energy. In fission reactions, a large atomic nucleus is split into smaller nuclei, also releasing energy.

Question 2: Two isotopes involved in fusion reactions are Deuterium (2H) and Tritium (3H).

Question 3: X is Th and Y is 231. Z is alpha. 234 = 231 + 4. The number of protons, neutrons, and electrons must be equal on both sides of the reaction to conserve mass.

Question 4A: A nuclear decay reaction has occurred, emitting an alpha particle.

Question 4B: Yes, transmutation has occurred because the element Th has changed into the element Pa.
