What is the average mass of the mixture of an elements isotopes?
All of the isotopes in an element's atomic masses divided by the amount of isotopes there are is the weighted-average mass of the mixture of an elements isotopes.
Why the mass numbers on the periodic table of elements are rarely whole numbers?
Elements also possess isotopes. So their average atomic mass is rarely whole number.
What is the mass number of sliver?
Mass number is a property of isotopes, not elements themselves. Naturally occurring silver is a mixture of isotopes with mass numbers 107 and 109, with an average atomic mass of 107.9.
Why are mass numbers of elements rarely whole?
Mass numbers of elements are rarely whole numbers because they account for the isotopes of an element, which have different numbers of neutrons. The atomic mass listed on the periodic table is a weighted average of the masses of all naturally occurring isotopes, factoring in their relative abundances. As a result, this average often results in a non-integer value, reflecting the contributions of both stable and unstable isotopes.
Why elements don't have whole numbers?
do you mean the why is the average atomic mass not a whole number? because if that is your question, then the answer is that each element has multipal isotopes and the mass you see on the periodic table is the average of all the isotopes together. So there has to be a decimal on the periodic table of elements
What is the average of the mass numbers of isotopes of an element?
the atomic mass
What is the average mass of the isotope of an element?
the average mass numbers of the isotopes of an element
Name two elements have the same mass numbers?
No elements have the same average mass, but some isotopes are the same mass as other elements, For example Carbon-13 (an isotope of carbon) has the same mass as nitrogen-13 (which is also an isotope of nitrogen).
What do elements of isotopes have differently?
Because of the difference in mass number. Isotopes must have different numbers of neutrons.
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
What isotopes of uncharded elements have different numbers?
The atomic number of the isotopes of an element is identical; the mass number is different.
What are the atomic mass of elements rarely whole numbers?
1. First cause: the atomic weight is the sum of the weights of protons, neutrons ans electrons.; they don't have masses as integers.2. Second cause: also occurs the so-called mass defect.Not atomic mass for elements; atomic weight is correct.
