Why does tellurium have a larger atomic mass?

Why does tellurium have a larger atomic mass?

Naturally occurring tellurium is composed of eight isotopes of which the three with highest abundance are tellurium-126, tellurium-128 and tellurium-130. Since tellurium contains isotopes of masses higher than the iodine, the average atomic mass of tellurium is greater than that of iodine.

What element is the heaviest atomic mass?

Ununoctium is the heaviest element, but it is man-made. The heaviest naturally-occurring element is uranium (atomic number 92, atomic weight 238.0289). Heaviest Element in Terms of Density Another way to look at heaviness is in terms of density, which is mass per unit volume.

What does atomic mass tell us about the atom?

Atomic mass of an element tells us the number of times an atom of the element is heavier than of the mass of an atom of carbon-12. A unit suitable for the mass of atoms and the mass of subatomic particles is the atomic mass unit (u).

What determined atomic mass?

Scientists determine the atomic mass by calculating the mean of the mass numbers for its naturally-occurring isotopes . Often, the resulting number contains a decimal.
