How much difference is there between the mass/charge ratio of ions of the same element? Is it the same, or does it depend on other factors?
Mass/Charge Ratio of Ions: How Much Difference?

In summary, the discussion is about the difference in mass/charge ratio of ions of the same element and whether it depends on other factors. The clarification is made that the topic is indeed about ions and not atoms. The conclusion is that different ions of the same element can have different mass/charge ratios and both mass/charge and charge/mass ratios are important in mass spectrometry.

Did you mean "ions" of the same element (as noted by the thread title)? Or perhaps "isotopes"?StandardBanana said:
Regardless, mass/charge ratio should be solely dependent on those two quantities.

Yes I do mean ions, thank you for clearing that up
Does this mean that ions of the same element can have different mass/weight ratios?

No problem, and sorry for not mentioning before... Welcome to the Forums!StandardBanana said:Yes I do mean ions, thank you for clearing that up
Does this mean that ions of the same element can have different mass/weight ratios?
Yes, different ions of the same element have different mass/charge ratios.
Also, note, charge/mass ratio is also used sometimes, which is just the inverse of mass/charge. Both are important in mass spectrometry.
1. What is the mass/charge ratio of ions?
The mass/charge ratio of ions refers to the ratio of an ion's mass to its charge. It is typically represented by the symbol m/z and is commonly used in mass spectrometry to identify and analyze different ions.
2. How is the mass/charge ratio of ions calculated?
The mass/charge ratio of ions is calculated by dividing the mass of the ion by its charge. This can be done using a mass spectrometer, which measures the mass and charge of ions in a sample and calculates their ratio.
3. Why is the mass/charge ratio of ions important in mass spectrometry?
The mass/charge ratio of ions is important in mass spectrometry because it allows for the identification and analysis of different ions in a sample. By measuring the mass/charge ratio, scientists can determine the mass and charge of an ion, which provides information about its chemical structure and composition.
4. How much difference can there be in the mass/charge ratio of ions?
The mass/charge ratio of ions can vary greatly depending on the type of ion and the elements it is composed of. In general, the difference in mass/charge ratio between ions is relatively small, but it can vary significantly depending on the size and complexity of the ion.
5. How is the mass/charge ratio of ions affected by the presence of other ions or molecules?
The mass/charge ratio of ions can be affected by the presence of other ions or molecules in a sample. This is because the presence of other ions or molecules can alter the electric field in the mass spectrometer, which can impact the trajectory of ions and affect their mass/charge ratio measurements. However, modern mass spectrometers are designed to minimize these effects and accurately measure the mass/charge ratio of ions even in complex samples.
