Yes, weighted by how often the isotopes are found in nature.
it is the weighted average of the masses of an element's isotopes.
the Atomic Mass
The number with a decimal point in each element square on the periodic table represents the average atomic mass of that element. It takes into account the mass of different isotopes of the element and their relative abundance in nature.
Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei. This leads to variations in atomic mass for isotopes of the same element.
The two notations represent atoms that are isotopes of the same element is 121 Sn and 119 Sn. The atomic mass of an element is defined as the weighted average mass of that elements naturally occurring isotopes.
the average mass numbers of the isotopes of an element
Its the average of the weight of the different isotopes of that element.
Isotopes have a different amount of Neutrons. The atomic mass is the sum of Protons and Neutrons. Therefore having a different number of Neutrons makes the atomic mass greater. Or vice versa. Boom. Solved.
There is an average atomic mass because all atoms of the same element do not have the same amount of neutrons (isotopes), therefore variations in atomic mass exist. The average atomic mass of an element is the estimated average of all the atoms of the same element, given the average of different isotopes in a scientific sample.
The average atomic mass takes into account the different isotopes of an element and their relative abundance, while the mass of an individual atom is specific to that particular isotope. The average atomic mass is a weighted average based on all isotopes present in a sample, providing a more accurate representation of the element's mass in nature.
average atomis mass
Isotopes of the same element have different numbers of neutrons and mass.
isotopes of the same element have different mass number
it is the weighted average of the masses of an element's isotopes.
the atomic mass
They are isotopes of that element, they have different neutron numbers.
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.
