Isotope

An Isotope.

ISOTOPE

Isotope mass

The mass of this isotope.

Let's say we have the isotope that's 24.

So we're actually measuring each isotope as a different one.

The number of neutrons this isotope has.

Even though the nickel isotope, , is more stable, the iron isotope is an order of magnitude more common.

The principal natural isotope of aluminium is aluminium 27.

Because of this, there are concerns about the safety of thorium mantles.

For 80 of the chemical elements, at least one stable isotope exists.

U 235 is the main fissile isotope of uranium.

For natural uranium, about 49 of its alpha rays are emitted by each of 238U atom, and also 49 by 234U (since the latter is formed from the former) and about 2.0 of them by the 235U.

The radiological toxicity of technetium (per unit of mass) is a function of compound, type of radiation for the isotope in question, and the isotope's half life.

Isotopes 59Co is the only stable cobalt isotope and the only isotope to exist naturally on Earth.

This box is used to specify the half life of the above isotope.

This label displays the atomic mass of the isotope in grams per mole.

Radium 223 is an isotope which decays and is not metabolised.

Further separation was carried out by ion exchange, yielding a certain isotope of curium.

Its most stable isotope 271Sg has a half life of 1.9 minutes.

those are each called isotopes I just view them in my head as versions of an element.

It will contain the radioactive technetium isotope in an amount called 740 1110 MBq.

The chemically identical uranium 235 has to be physically separated from the more plentiful isotope.

The shortest lived isotope is 258Sg which also decays through alpha decay and spontaneous fission.

Within a single element, the number of neutrons may vary, determining the isotope of that element.

The kit allows the coupling of antibody ibritumomab tiuxetan with the radioactive isotope yttrium 90Y (radiolabelling).

A line selectable laser produces discrete wavelengths within one laser transition and is not considered tunable .

The term isotope is formed from the Greek roots isos (ἴσος equal ) and topos (τόπος place ), meaning the same place .

In many cases members of the decay chain are far more radioactive than the original nuclide.

Following administration of radiolabelled sirolimus, radioactivity is excreted in the milk of lactating rats.

Following administration of radiolabelled sirolimus, radioactivity is excreted in the milk of lactating rats.

Americium is not synthesized directly from uranium the most common reactor material but from the plutonium isotope 239Pu.

The percentage of atoms occurring that are of this isotope type. Also called abundance.

This box is used to specify the isotope of the above element on which calculation is performed.

Following administration of radiolabelled sirolimus, radioactivity is excreted in the milk of lactating rats.

Following administration of radiolabelled sirolimus, radioactivity is excreted in the milk of lactating rats.

Because apparently you can't have this fragile isotope of Lithium 6 in the atmospheres of sun like stars.

The radioactive isotope molybdenum 99 is used to generate technetium 99m, which is used for medical imaging.

The nucleus of the most common isotope of the hydrogen atom (with the chemical symbol H ) is a lone proton.

Hence after two half lives have passed only 25 of the isotope is present, and so forth.

Brown dwarfs are generally considered stars due to their ability to fuse deuterium, a heavier isotope of hydrogen.

Although many false claims of its discovery were made over the years, the element was first synthesized by Edwin McMillan and Philip H. Abelson at the Berkeley Radiation Laboratory in 1940.

The positive muon, in this context, can be considered a pseudo isotope of hydrogen with one ninth of the mass of the proton.

Irradiation by the emitted beta particles from 90Y occurs in a radius of 5 mm around the isotope.
