Density of Radium
Density of Radium is an important parameter among its mechanical properties. Radium 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 5.50 g/cm3.
Viscosity of Radium cannot be determined, as the concept of viscosity is only applicable to fluid (liquid state) substances.
Tensile Strength of Radium
Tensile strength of Radium 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 Radium with other metals. The extent of application of any metal is determined by its tensile strength.
