Plutonium has no natural isotopes. All plutonium isotopes are artificially produced through nuclear reactions.
Today are known approx. 3 000 radioactive isotopes, natural or artificial.
The number of neutrons in an aluminum ion can vary depending on the isotope. The most common isotope of aluminum is 27Al, which has 14 neutrons. However, other isotopes of aluminum exist with different numbers of neutrons.
There are two stable isotopes of gallium: gallium-69 and gallium-71. Additionally, there are several radioactive isotopes of gallium, but they are unstable and decay over time.

These are the natural isotopes of C, O and H.
Aluminum, like all other elements, comes in a variety of isotopes, and that is normal.
One.

All elements have some isotopes that undergo radioactive decay, the question is how fast.Aluminum comes in three major isotopes, each with their own half-life:Al-26: 730000 years - 0% in natural aluminumAl-27: Stable - 100% in natural aluminumAl-28: 2.3 minutes - 0% in natural aluminumSo as natural aluminum is 100% Al-27 it does not undergo radioactive decay
yes
Plutonium has no natural isotopes. All plutonium isotopes are artificially produced through nuclear reactions.
Uranium has 3 natural isotopes (234, 235, 238) and 26 artificial isotopes.All the isotopes of uranium are radioactive.
Today are known approx. 3 000 radioactive isotopes, natural or artificial.
yes. e.g. Al2O3
There are three natural isotopes.
