Which type of radioactive decay has the net effect of changing a neutron into a proton? Which type of decay has the net effect of turning a proton into a neutron?

Short Answer

Expert verified
Beta-minus decay has the net effect of changing a neutron into a proton, and beta-plus decay has the net effect of turning a proton into a neutron.

Step by step solution

01

Identify the radioactive decay that changes a neutron into a proton

In beta-minus decay, a neutron is converted into a proton, while emitting an electron (beta particle) and an electron antineutrino. The equation for beta-minus decay is: \[ n \rightarrow p + e^{-} + \bar{\nu_e} \] Here, 'n' stands for neutron, 'p' for proton, \(e^{-}\) for the emitted electron (beta particle), and \(\bar{\nu_e}\) for the electron antineutrino.
02

Conclusion for neutron to proton transformation

Beta-minus decay is the type of radioactive decay that has the net effect of changing a neutron into a proton. Now, let's identify the radioactive decay that changes a proton into a neutron.
03

Identify the radioactive decay that changes a proton into a neutron

In beta-plus decay, also known as positron decay, a proton is converted into a neutron while emitting a positron (positive electron) and an electron neutrino. The equation for beta-plus decay is: \[ p \rightarrow n + e^{+} + \nu_e \] Here, 'p' stands for proton, 'n' for neutron, \(e^{+}\) for the emitted positron, and \(\nu_e\) for the electron neutrino.
04

Conclusion for proton to neutron transformation

Beta-plus decay is the type of radioactive decay that has the net effect of turning a proton into a neutron. In summary, beta-minus decay has the net effect of changing a neutron into a proton, and beta-plus decay has the net effect of turning a proton into a neutron.

Scientists have estimated that the earth's crust was formed \(4.3\) billion years ago. The radioactive nuclide \({ }^{176} \mathrm{Lu}\), which decays to \({ }^{176} \mathrm{Hf}\), was used to estimate this age. The half- life of \({ }^{176} \mathrm{Lu}\) is 37 billion years. How are ratios of \({ }^{176} \mathrm{Lu}\) to \({ }^{176} \mathrm{Hf}\) utilized to date very old rocks?

A reported synthesis of the transuranium element bohrium (Bh) involved the bombardment of berkelium-249 with neon-22 to produce bohrium-267. Write a nuclear reaction for this synthesis. The half-life of bohrium-267 is \(15.0\) seconds. If 199 atoms of bohrium-267 could be synthesized, how much time would

Much of the research on controlled fusion focuses on the problem of how to contain the reacting material. Magnetic fields appear to be the most promising mode of containment. Why is containment such a problem? Why must one resort to magnetic fields for containment?

Define "third-life" in a similar way to "half-life", and determine the "third- life" for a nuclide that has a half-life of \(31.4\) years.

Phosphorus-32 is a commonly used radioactive nuclide in biochemical research, particularly in studies of nucleic acids. The half-life of phosphorus-32 is \(14.3\) days. What mass of phosphorus-32 is left from an original sample of \(175 \mathrm{mg}\) \(\mathrm{Na}_{3}{ }^{32} \mathrm{PO}_{4}\) after \(35.0\) days? Assume the atomic mass of \({ }^{32} \mathrm{P}\) is \(32.0 \mathrm{u}\).
