BIO 152 LAB 9 EXAMINATION 2026 STUDY
GUIDE QUESTIONS AND ANSWERS FULL
REVIEW GRADED A+
◉ Strong Force Answer: The glue that holds the nucleus of an atom
together, much stronger than Electrostatic Force, can only be split by
Fission
◉ Fission Reactions Answer: The splitting of proton and neutrons in
a nucleus
◉ Mass Number Answer: Sum of Protons and Neutrons
◉ Isotopes Answer: Atoms with the same number of protons and
electrons, but a different number of neutrons
◉ Unstable Isotopes Answer: Undergo radioactive decay, releasing
energy
◉ Radioactive Decay Answer: Process in which half of the nuclei in a
sample will decay over a period of time by loosing energy by
emission of alpha, beta, and/or gamma radiation
, ◉ 3 Types of Radioactive Decay Answer: Alpha, Beta, Gamma
◉ Alpha Decay Answer: Occurs when an alpha particle is released
from the nucleus: 2 Protons, 2 Neutrons of He: Changes identity of
the radioactive element
◉ Alpha Decay Example Answer:
◉ Alpha Decay Strength Answer: Weak: can be stopped by paper
◉ Beta Decay Answer: When a neutron is transmuted into an
electron and a new proton, where the electron is released as energy
◉ Beta Decay Example Answer:
◉ Beta Decay Strength Answer: Can be stopped by a sheet of
aluminum foil
◉ How is the frequency of radioactive decay determine? Answer: by
the Half-Life of the element
◉ Half-Life Answer: The time required for one half of the atoms in a
sample of a radioactive isotope to decay
