Neons mass number
WebRelative atomic mass. The relative atomic mass ( Ar) of an element is the average mass of the naturally occurring atoms of the element. This quantity takes into account the percentage abundance of all the isotopes of an element which exist. Given that the percentage abundance of is 75% and that of is 25%, calculate the A r of chlorine. WebIsotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. Mass numbers of typical isotopes of …
