Nuclear Chemistry Exam|| Latest
Exam Questions And Well Verified
Correct Answers||Already Graded A+
alpha particle -CORRECT ANSWER a helium nucleus that is emitted from a
radioactive atom.
beta particle -CORRECT ANSWER a high speed electron that is emitted from a
radioactive atom. Neutron is transformed into a proton
gamma particle -CORRECT ANSWER a high-energy photon (particle of light) that is
emitted from a radioactive nucleus. They have zero mass
What stops alpha? -CORRECT ANSWER paper
nuclear radiation -CORRECT ANSWER the emission of alpha particles, beta particles,
or gamma rays from the nucleus of an atom
mass number -CORRECT ANSWER the number of protons and neutrons in the
nucleus of an atom
atomic number -CORRECT ANSWER the number of protons in the nucleus of an atom.
isotope -CORRECT ANSWER Atoms that have the same number of protons (and are
therefore the same element) but different numbers of neutrons.
radioisotope -CORRECT ANSWER an atom that emits alpha particles, beta particles,
and/or gamma rays.
stable isotope -CORRECT ANSWER an "ordinary" element: does not break down and
does not emit particles or rays.
Using the periodic table and your knowledge of nuclear chemistry terminology, give the
symbol for lead-212 -CORRECT ANSWER
fission -CORRECT ANSWER breaking a large nucleus into smaller nuclei.
This is what releases the energy in nuclear reactors and atomic bombs.
What subatomic particle causes the nuclear chain reaction in nuclear reactors and
atomic bombs? -CORRECT ANSWER The neutron
