It emits an electron and an antineutrino and increases by one in atomic number while ending up with one fewer neutrons, or it emits a positron and a neutrino and decreases by one in atomic number while ending up with one more neutron. In both cases the total number of protons and neutrons remains unchanged, and the number of orbital electrons will eventually change to match the new atomic number.

Can the half life of a radioactive isotope decrease as the isotope decays?
No, the half-life of a radioactive isotope does not decrease as the isotope decays. That half-life remains constant. It's the amount of the substance that decreases as the isotope decays.
When a radioactive isotope decays it gives off energy and produces a product called?
Another isotope is produced.
What is the first radioactive element that forms when uranium 238 decays?
The isotope 234 Th.
Which radioactive isotope is used to monitor the thickness of metal strips?
Caesium-137 as it decays by beta emission.
When a radioactive tracer is used why is it best to use a radioactive isotope that decays into a stable isotope?
The principle behind the use of radioactive tracers is that an atom in a chemical compound is replaced by another atom, of the same chemical element. The substituting atom, however, is a radioactive isotope. This process is often called radioactive labeling.

What is the definition of a parent isotope?
according to google XD, this is the radioactive atom that decays to product a daughter isotope

How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
What happens when radioactive element decays?
Carbon gets released
What is the sample of the radioactive isotope 131I decays its half-life?
Iodine-131 has a half-life of about 8 days.

What is a dacay chain?
When a radioactive isotope decays, it may convert to another isotope which is, again, unstable. The "decay chain" refers to the complete list of all the intermediate products, until a stable isotope is reached.
What is the similarity of radioactive isotope and radioactive dating?
Radioactive isotopes are used for radioactive dating. For example, you would use radioactive isotope Carbon-14 to date anything under 70,000 years that was once living. Radioactive isotopes decay from their parent isotope to daughter isotope at a constant rate (under any circumstances). The rate at which a parent isotope decays to its daughter isotope is considered one half life. Carbon-14 has a half life of 5730 years and its daughter isotope is Nitrogen-14. In order to determine how old something is you have to find out how much of the parent isotope is present in relation to the daughter.
What type of nuclear radiation is emitted when carbon-14 decay?
Yes, carbon 14 is a radioactive isotope.
