Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes, the atomic mass of an element takes into account the relative abundance of each isotope of that element. This is because atomic mass is the weighted average of the masses of all isotopes of an element based on their natural abundance.
What is the name of the isotope that has 7 neutrons and 6 electrons?
The natural isotope of carbon 13C (abundance 1,1 %) has 6 protons, 6 electrons and 7 neutrons.
The atomic mass of an atom is equal to the sum of the numbers of what?
The mass number of an atom is the average of all it's isotopes in ratio to how often an isotope occurs naturally (abundance). An isotope is a variant of an element that has a different number of neutrons, therefore causing the atom to have a different mass. The percent abundance of an isotope is converted to a fraction, and multiplied by the mass of the isotope. Then all the factional masses of different isotopes are added together. Atomic mass = (mass isotope 1)x(fractional natural abundance of isotope 1) + (mass isotope 2)x(fractional natural abundance of isotope 2) + (mass isotope 3)x(fractional natural abundance of isotope 3) For example: Hydrogen has 3 naturally occurring isotopes: Protium - Abundance - 99.985% (.99985) Mass - 1.0078 Deuterium - Abundance - .015% (.00015) Mass - 2.014 Tritium - Abundance - 0% (.000) Mass - 3.016 Atomic mass number of Hyrdogen = (.99985)(1.0078) + (.00015)(2.014) + (.000)(3.016) = 1.00795 Go look up the mass number of Hydrogen on the periodic table and it says 1.008
What is the defined atomic mass in amu of this isotope?
The atomic mass of an isotope is the weighted average mass of all the isotopes of that element based on their natural abundance. It is expressed in atomic mass units (amu).
How can one determine the natural abundance of an isotope?
One can determine the natural abundance of an isotope by analyzing the ratio of the isotope to the total amount of that element in a sample using techniques such as mass spectrometry or nuclear magnetic resonance spectroscopy.
What is the formula to find the natural abundance?
In chemistry, natural abundance refers to the abundance of isotopes of a chemical element that is naturally found on a planet. Its formula is given as: abundance of isotope = average atomic weight of the element / exact weight of isotope.
What is is relative abundance?
The concentration of each isotope of a natural chemical element.
How do you calculate the abundance of boron isotopes?
To calculate the abundance of boron isotopes, you would typically need to know the masses and natural abundances of each isotope. You can then use these values to calculate a weighted average, taking into account the abundance of each isotope relative to its mass. The formula for calculating isotopic abundance involves multiplying the natural abundance of each isotope by its mass and then summing these values for all isotopes.
If an element has three isotopes with known natural abundance percentages what other information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope
Ga-69 and Ga-71 Which isotope occurs in greater abundance?
Ga-69 occurs in greater abundance, with a natural abundance of about 60.1%, compared to Ga-71, which has a natural abundance of about 39.9%.

Which isotope occurs in greater abundance in chlorine?
Chlorine-35 is the most abundant isotope of chlorine.
What is the natural abundance of oxygen-15 and oxygen-16?
Oxygen-16 is the most abundant isotope of oxygen, accounting for about 99.76% of natural oxygen. Oxygen-15, on the other hand, is much less common, with a natural abundance of only about 0.04%.
What is the natural abundance for iodine-131?
The natural abundance of iodine-131 is zero, as it is a radioactive isotope that is not naturally occurring in the environment. It is typically produced artificially in nuclear reactors for use in medical and industrial applications.
