Quantum, Atomic, and Nuclear Physics
What effect does increasing atomic number have on an element's alpha decay energy, assuming all other factors remain constant?
The alpha decay energy decreases as higher atomic numbers lead to lower nuclear binding energies being overcome during emission.
The energy released in alpha decay typically increases with higher atomic numbers due to greater nuclear binding energy needing to be overcome.
Increasing atomic number leads to exponential growth in alpha decay energy because each additional proton dramatically increases repulsion forces within nuclei.
The energy released remains constant regardless of changes in atomic number due to conservation laws.
What type of radiation is emitted when a neutron in an unstable nucleus decays into a proton?
Positron emission.
Gamma radiation.
Beta radiation.
Alpha radiation.
After undergoing gamma decay, what can be said about the identity of the resulting atom compared to its original state before decay?
Its identity changes due to loss of energy causing isotopic shift despite having same number of protons or neutrons.
It becomes more stable as it gains both energy and mass through emission of high-energy photons.
Its chemical properties are altered even though its nuclear composition remains constant after release of photons
The identity remains unchanged because only energy in photon form has been emitted with no change to protons or neutrons.
In assessing limitations of a simple radioactive decay model applied to medical radioisotopes used for imaging, what would be an essential consideration related to bodily interactions?
Expecting no other forms of radioactivity present within patients' bodies except those administered medically.
Belief that all patients will exhibit identical physiological responses to injected radioisotopes.
The assumption that radioisotopes remain stable and undecayed within the body until imaged.
Biological uptake and excretion rates altering expected distribution times throughout tissues and organs.
In an RLC series circuit, if the resistance is doubled while the capacitance and inductance remain constant, what happens to the resonant frequency of the circuit?
The resonant frequency increases by a factor of √2.
The resonant frequency remains unchanged.
The resonant frequency is doubled.
The resonant frequency is halved.
Which equation represents the decay constant in terms of half-life?
