What is the chain of neptunium breaking down?
The neptunium decay series is finished with the stable isotope thallium-205.
What would Americium transmute into if it expelled an alpha particle?
For example americium-241 decay to neptunium-237 and americium-243 decay to neptunium-239.
What element is formed when neptunium atoms fall apart?
For the most common isotope of neptunium, Np-237, the decay daughter is protactinium-233.Each isotope has another type of decay.
When one neptunium isotope undergoes an alpha decay what does it become?
Npn decays to Pan-4 and alpha. Only isotopes 234, 235, and 237 of neptunium can undergo alpha decay, the others decay by beta-, beta+, K capture, and/or gamma decay. So the only products of neptunium alpha decay can be protactinium isotopes 230, 231, or 233.
Which daughter element is produced from the alpha decay of americium 241?
The alpha decay of americium-241 produce neptunium-237.
Does ytterbium form when neptunium disintegrates?
It is possible. Neptunium can decay by spontaneous fission, and ytterbium is a possible daughter, although vanadium would have to be the co-daughter. (93NP --> 70Yb + 23V) It seems unlikely, however, as the split would more likely be closer to centerline mass.
What chemistry elements are named after mythological characters?
Argon, Titanium, Promethium, Tantalum, Mercury, Actinium, Plutonium, Neptunium, Uranium
What are elements that are made in laboratory?
Manmade elements. These have traditionally been considered to be: Technetium, Promethium, Neptunium, and all elements beyond Neptunium. However trace levels of several of these have since then been detected naturally.
How do you use the periodic table to find what forms when neptunium disintegrates?
After an alpha decay the atomic number of the new element formed is less with 4.
What form does neptunium likes to take on naturally?
Neptunium is a solid metal.
What are the elements that make neptunium?
Neptunium itself is an element, the simplest form of matter.
Why are technetium neptunium and promethium considered natural elements even though they are not found on earth?
In the last years technetium, prometium, neptunium and plutonium was found in the nature but in extremely low concentrations.Because they are found in the universe. They have been observed in the spectrum of certain stars.
What element is Np?
The element with chemical symbol Np is Neptunium. Neptunium is a radioactive Lanthanide and is part of the unofficial Promethium family. It has 93 electrons in 7 shells and is next to Uranium and Plutonium.
Which element can neptunium combine to make an explosion?
Any element; neptunium can form himself a critical mass.
Where does the plutonium come from?
Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.
Why are technetum promethium and neptunium considered naturally occurring elements even though they are not found on earth?
These elements exist also naturally - in infinitesimal amounts - in the Earth crust.But practically are artificial elements.
Where does the element plutonium come from?
Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.
