Neptunium is a hard metal, having a bulk modulus of 118 GPa, comparable to that of manganese. [9] Neptunium metal is similar to uranium in terms of physical workability. When exposed to air at normal temperatures, it forms a thin oxide layer. This reaction proceeds more rapidly as the temperature increases. [8]

Its unusual properties include ability to negate gravity, allowing a person wearing an object made of it, such as a belt, to fly. Nth metal also protects the wearer from the elements and speeds healing of wounds, [56] increases their strength, and protects them from temperature extremes. It has many other properties that are yet to be revealed ...
