Neptunium is a chemical element. Atomic Number: 93, Atomic Symbol: Np. Neptunium is fissionable. For this, it is used as fuel in a fast neutron reactor or in a nuclear weapon.
Neptunium is not a magnet.
The three common compounds of neptunium are neptunium dioxide (NpO2), neptunium trichloride (NpCl3), and neptunium tetrafluoride (NpF4).
Neptunium is a solid metal at room temperature.
Neptunium is a member of the actinides group.
The fresh surface of neptunium is silvery.
When neptunium atoms fall apart, they can form various isotopes of other elements. Neptunium decay series typically produce isotopes of uranium, thorium, and protactinium as the neptunium atom undergoes radioactive decay.
Neptunium trifluoride is an intermediate for the preparation of neptunium metal.
Neptunium is a metal.
The three common compounds of neptunium are neptunium dioxide (NpO2), neptunium trichloride (NpCl3), and neptunium tetrafluoride (NpF4).
Neptunium is an individual element; isotopes of neptunium are not separated.
Neptunium(IV) oxide or neptunium dioxide is the chemical compound composed of neptunium and oxygen with the formula NpO2. It forms dark olive[4] green cubic crystals[1].
Electron configuration of neptunium: [Rn]7s26d15f4
No use today; neptunium trifluoride is used to prepare neptunium metal.
Neptunium is an artificial element.Amounts of natural neptunium are absolutely nonsignificant.
Yes, neptunium is a metal.
Neptunium is not in foods.
Neptunium atom is neutral; ions of neptunium have valences between 3 and 7.
Neptunium has 93 protons.
