What type of radioactive decay should be expected from aluminum 28?
alpha decay
The resulting aluminium-28 isotope will then decay via alpha decay. When isotopes undergo alpah decay, their nucleus emits an alpha particle, which is essentially the nucleus of a helium-4 atom.
Does aluminum undergo decay?
One of the isotopes of aluminium, namely aluminium-26 (26Al), contains 13 protons and 13 neutrons in its nucleus. Unlike the stable isotope aluminium-27 (27Al), which comprises an extra neutron, 26Al is radioactive and decays with an exponential lifetime of about one million years.
What does aluminum decay into?
Al is a radioactive isotope that decays into 26Mg, a stable isotope, with a half-life of 0.73 million years.
What type of decay does aluminum-26 undergo?
Aluminium-26 (26Al, Al-26) is a radioactive isotope of the chemical element aluminium, decaying by either positron emission or electron capture to stable magnesium-26. The half-life of 26Al is 7.17×105 (717,000) years….Aluminium-26.

Why does aluminium foil stop beta decay?
Beta particles travel faster than alpha particles and carry less charge, so they interact less readily with the material through which they pass. They can be stopped by a few millimetres of aluminium.
What happens when aluminum oxidizes?
Aluminum has a very high affinity to oxygen. When a new aluminum surface is exposed in the presence of air or any other oxidizing agent, it quickly develops a thin, hard film of aluminum oxide (or hydrated oxide in non-stagnant water). This aluminum oxidation is precisely what makes aluminum so corrosion-resistant.
How are radioisotopes decay in the 232 / 90 Th decay series?
In the 232/90 Th decay series there are six radioisotopes that decay by alpha emission, including Th-232 itself, and four radioisotopes that decay by beta emission. The final product of this series is a stable isotope.
What is the biological effect factor of alpha radiation?
The biological effect factor of alpha radiation is 20. A 1 mrem B) 1000 mrems C) 2.5 mrems D) 2500 mrems E) 100 mrems 000 S 36. A sample of cerium-141 for a diagnostic test was dissolved in saline solution to an activity of 4.5 mCi/mL.
What kind of isotope is produced when aluminum-27 is bombarded with a neutron?
When aluminum-27 is bombarded with a neutron, a gamma ray is emitted. What radioactive isotope is produced? aluminum-28
