Mass of the protons + Mass of the neutrons
The Truth? Well, there is no element with that atomic weight. The highest atomic weight is 262.11 Sorry!
The Atomic Mass of an element is the numerical average of all the masses of the naturally occurring isotopes of that element proportionately. Man made elements do not count in supposedly. IE: If we have an element with atomic weight 100 and we have an isotope of that element with atomic weight 102 and if they occurred equally in nature then the Atomic Mass would be 101.
The element of Antimony (Sb) would have the atomic weight of 121.75.
The protons and neutrons are the main contributors to the weight of an atomic element.
All elements have an (atomic) weight or mass.
The atomic weight of an element is derived from the atomic masses of the isotopes of this element and from the percentage of these isotopes. The correct terms are: - atomic weight for elements - atomic mass for an isotope
Vanadium is the element that has an atomic weight of 50.942.
The atomic weight (not mass) of a chemical element is calculated considering the isotopic composition of the element and the atomic masses (not weights) of these isotopes.
Petroleum is not an element and therefore has no atomic weight!
Selenium (Se) has an atomic weight of 79,04.
a fly is not an element so it does not have an "atomic" weight. It does have a mass or weight however
Average weight of an element expressed in Atomic Mass units.
