If 40 percent of the isotopes of an element have a mass of 16 atomic mass and 60 percent of the isotopes have a mass of 18 atomic mass what is the average atomic mass?
((16x40) +(18x60))/100 = 17.2
How do the atomic number of the different isotopes an element compare?
The atomic number is the same for the all isotopes of a chemical element.
How do you calculate the atomic mass of an element with different isotopes?
To calculate average atomic mass from different isotopes of an element, we take into account the relative atomic masses of isotopes and their relative abundance on Earth. The following formula is used to calculate the needful : atomic mass = mass of isotope x percent abundance + mass of isotope x percent abundance / 100 (whole expression divided by 100)
Does an isotope of an element have a different atomic mass?
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
How the atomic mass of an element is affected by the distribution of its isotopes in nature?
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.

Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
What is a similarity and a difference between isotopes of an element?
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
Does isotopes affect the physical properties of the element?
Isotopes contribute to the atomic weight of a chemical element.
The various atomic weights of the same element are called?
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
How you calculate the relative atomic weight of uranium?
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
What is the difference between atomic mass number and atomic number?
Atomic mass number is the average atomic mass for that element, which is : All the isotopes' masses known for that element averaged up. Atomic number is the element's "identity", the number of protons the element and all its isotopes have. All the isotopes of a given element will have different number of electrons and neutrons, but the protons of the element never will change.
