no. of protons
The weight average atomic mass of an element is a weighted average of the masses of all its isotopes, taking into account their natural abundance. This gives a more accurate representation of the actual mass of an element in the natural world.
The element of Antimony (Sb) would have the atomic weight of 121.75.
Sulfur (32.065)
The protons and neutrons are the main contributors to the weight of an atomic element.
All elements have an (atomic) weight or mass.
The number of protons in the nucleus of an element gives that element its ATOMIC NUMBER.
Vanadium is the element that has an atomic weight of 50.942.
Petroleum is not an element and therefore has no atomic weight!
a fly is not an element so it does not have an "atomic" weight. It does have a mass or weight however
Selenium (Se) has an atomic weight of 79,04.
Atomic weight is not the same as atomic number for any element except hydrogen; this is the only element that has a radioactively stable isotope with no neutrons.
The element with an atomic weight of 35.453 is chlorine (Cl).
