Heavy, radioactive silvery metal. See link below
Neptunium is a solid metal.
At room temperature neptunium is a solid metal.
- valences of neptunium: 3 to 7- Pauling reactivity: 1,36- as a powder is pyrophoric- can react with the majority of non metals- react with acids- it is easily oxidized
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 physical properties of the meteors are that they are rocky and parts of other asteroids.
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].
Plutonium and neptunium are two elements that have properties similar to uranium. They belong to the same actinide series and share similar chemical and physical characteristics, such as radioactive decay and the ability to form multiple oxidation states.
Depth, density, and dynamical ellipticity are physical properties of Earth.
it is iron
Neptunium is ductile and malleable; see also at: http://www.onemine.org/search/summary.cfm/Institute-of-Metals-Division--Fabrication-of-Neptunium237-Wire-by-Extrusion-TN?d=25FB0091D9A4A9A7F667E4C439E0ED9006727D6BC0570438EA2470D65AC3E9C126367
Neptunium is a radioactive actinide element with properties similar to uranium. It can exist in multiple oxidation states, such as +3, +4, +5, +6, and +7. Neptunium compounds are typically soluble in water and exhibit a variety of colors depending on the oxidation state.
Some antonyms for physical properties are abstract properties, immaterial properties, or conceptual properties. These terms describe characteristics that are not related to the physical attributes of an object or substance.
