Thallium is a naturally occurring element in the Earth's crust. It is not a man-made element.
Thallium(III) nitrate is Tl(NO3)3. Thallium(I) nitrate is TlNO3.
To calculate the atomic mass of thallium, you need to consider the weighted average of the isotopes of thallium found in nature, based on their abundance. You multiply the mass of each isotope by its relative abundance, then sum these values to get the atomic mass. The atomic mass of thallium is approximately 204.38 grams per mole.
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
