neptunium

The decay chain of U itself is in the neptunium series.

The element 93 was synthesised in 1940 and named neptunium.

The symbol Np was later used for the element neptunium.

The actual element was discovered several years later, and assigned the name neptunium.

It is not believed that an actual weapon has ever been constructed using neptunium.

This decay chain is known as the neptunium series.

For the outer planets, there are uranium, neptunium, and plutonium.

This is how elements such as neptunium, plutonium, and americium are made.

Neptunium has valence states from 3 to 7, which can be simultaneously observed in solutions.

Neptunium is very reactive when in contact with oxygen, steam, or acid.

Neptunium is a metal and a byproduct of uranium.

"And the neptunium series, which goes to bismuth 209.

Like plutonium, neptunium has a high affinity for soil.

Neptunium is a chemical element with the symbol Np and atomic number 93.

Thus, all primordial neptunium should have decayed by now.

Their production has expanded the periodic table significantly, the first of these being neptunium, synthesized in 1939.

Neptunium is a chemical element that has the symbol Np on the periodic table.

Due to its long half-life, neptunium becomes the major contributor of the total radiation in 10,000 years.

"Some trace elements of neptunium, which indicates a transmutation reaction.

Just before it died, the reading shows increased antimatter and traces of neptunium, which we've seen near the gravity sink.

This criterion includes plutonium, uranium, americium, and neptunium among others.

Neptunium does not have any biological role.

Neptunium (Np) is an artificial element, and thus a standard atomic mass cannot be given.

The 4n + 1 chain of Np-237 is commonly called the "neptunium series."

Other elements that contaminate the site include neptunium and americium, but little is known about their ability to travel in ground water.
