All elements have an (atomic) weight or mass.
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.
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.
Its not an element....
The element with an atomic weight of 35.453 is chlorine (Cl).
Iron (Fe) has an atomic weight of 55.845.
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.
