1.Describe what happens to a carbon-11 atom when it undergoes
positron emission.
The decay of a carbon-11 atom _____(options;changes a nuetron
into proton, changes proton into neutron, is hit with a neutron,
reconfigures its protons and neutrons) and this causes it to
emit______(options; a negatively charged electron sized particle, a
positively charged electron sized partticle, two atoms and several
neutrons, two neutrons and two protons)
2.An atom undergoes radioactive decay according to this
equation:
___.
What is the identity of...
The isotopes of promethium, 14459 Pr and 13459 Pr are unstable, and lie on opposite sides of the “line of stability”. Which of the following combinations is most likely to represent the type of decay for these isotopes? ///// So the answer is Beta decay for promethium-144 and positron decay for promethium-134 but can someone please explain why this is the case? N/Z's are 1.44 and 1.27 respectively... what's considered a "very high" versus a "high" versus a "low" ratio...
Consider the following beta-plus decay process, which is often used in positron emission tomography: 21 Na - 23 Net + - +ve The mass of sodium-22 is 21.9944364 u u The mass of neutral neon-22 is 21.9913831 u Question 14 Homework. Unanswered How much energy, in MeV, is released when one sodium-22 atom decays via the beta-plus decay process? _Mev Numeric Answer:
(a) Rank the following decays in order of the change in atomic number Z that occurs in the decaying nucleus, from most positive (greatest increase in Z) to most negative (greatest decrease in Z). If any two decays cause the same change in Z, state this. Explain how you made your ranking. (i) Alpha decay (emission of a 4He nucleus of charge +2e) (ii) Beta-minus decay (emission of an electron of charge –e and an antineutrino) (iii) Beta-plus decay (emission...
