Density of Protactinium
Density of Protactinium is an important parameter among its mechanical properties. Protactinium density is nothis but exact value of its mass(weight) per unit volume. Depending on the density, metals are classified as Heavy Metals. Its density at room temperature (near room temperature) is 15.37 g/cm3.
Viscosity of Protactinium cannot be determined, as the concept of viscosity is only applicable to fluid (liquid state) substances.
Tensile Strength of Protactinium
Tensile strength of Protactinium is Not Available. Its tensile strength reflects the effect of applied force to wrench the metal while it reaches the point where it breaks down into pieces. Its tensile strength is a deciding factor while comparing mechanical properties of Protactinium with other metals. The extent of application of any metal is determined by its tensile strength.
