If phosphorus had 16 neutrons what would change?
Not much. Phosphorus, atomic number 15, has an average atomic weight of about 31, indicating that most phosphorus atoms already have 16 neutrons.
The table below gives the atomic mass and the abundance of the two naturally occurring isotopes of chlorine. Which numerical setup can be used to calculate the atomic mass of the element chlorine?
To calculate the atomic mass of chlorine using its naturally occurring isotopes, you can use the formula: Atomic mass = (abundance of isotope 1 × atomic mass of isotope 1) + (abundance of isotope 2 × atomic mass of isotope 2). In this case, you would multiply the atomic mass of each isotope by its respective abundance (expressed as a decimal) and sum the results to find the weighted average atomic mass of chlorine.
How do you calculate the average relative atomic mass of neon?
To calculate the relative atomic mass of an element (which is by its definition an average), you need the mass number and relative abundance of each isotope present. Suppose we have the following data from the mass spectrometer: first isotope mn X, abundance A% second isotope mn Y, abundance B% third isotope mn Z, abundance C%. Then ram = (A/100 x X) + (B/100 x Y) + (C/100 x Z) If there are more than 3 isotopes, just do the same for each one and add all the expressions together.

What is the abundance of an isotope of atomic mass 64.9278?
There are three isotopes possible with mass number 65: Ni-65, Cu-65 and Zn-65. Only one of them:Cu-65 is occurring naturally (30.9%) with mass 64.92779 a.m.u.It is not a very accurate and reliable method to identify isotopes by mass. Atomic number or other properties of that element are more trustful.
If phosphorus had 16 neutrons what would change?
Not much. Phosphorus, atomic number 15, has an average atomic weight of about 31, indicating that most phosphorus atoms already have 16 neutrons.
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
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.
How do you calculate the relative abundance of two isotopes?
To calculate the relative abundance of two isotopes, you would divide the abundance of one isotope by the total abundance of both isotopes and then multiply by 100 to get a percentage.
How do you find percent abundance?
Percent abundance is calculated by determining the proportion of a specific isotope of an element relative to the total amount of all isotopes of that element. To find it, divide the number of atoms of the isotope by the total number of atoms of all isotopes, then multiply by 100 to convert it to a percentage. For example, if an element has two isotopes, with 75 atoms of isotope A and 25 atoms of isotope B, the percent abundance of isotope A would be (75 / (75 + 25)) × 100 = 75%.
If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element?
You would need to know the abundance of each isotope to find the average atomic mass of the element. The average atomic mass is calculated by multiplying the mass of each isotope by its relative abundance and then summing these values together.

In this case, you would multiply the atomic mass of each isotope by its respective abundance (expressed as a decimal) and sum the results to find the weighted average atomic mass of chlorine.
What isotope iodine iron phosphorus radium has the longest half-time?
Phosphorus, iron, and iodine all have at least one isotope that is stable, and any of these would do for the longest half life. In fact, the radioactive isotopes of phosphorus are all synthetic, so radioactive phosphorus is not found in nature.
What is the name of the instrument used to measure the relative abundance of an isotope?
A mass spectrometer is the instrument used to measure the relative abundance of an isotope. It does this by separating isotopes based on their mass-to-charge ratio and providing a qualitative and quantitative analysis of the isotopic composition of a sample.
If an element has three isotopes with unknown natural abundance percentages what other information is needed to find the average atomic mass of the element?
You would need the masses of each isotope and the abundance percentages of at least two of the isotopes. The average atomic mass is calculated by multiplying the mass of each isotope by its abundance, summing these values for all isotopes, and then dividing by 100.
How do you work out the percent abundance of two boron isotopes?
To determine the percent abundance of two boron isotopes, you would typically need experimental data from a mass spectrometry analysis. The percent abundance can be calculated by comparing the relative intensities of the peaks corresponding to the two isotopes in the mass spectrum. By dividing the intensity of each isotope by the sum of both isotopes' intensities and multiplying by 100, you can find the percent abundance of each isotope.
