you can measure the speed by timing time-of-flight, you know the charge on the (ionized) atom, you know the strength of the magnetic field. You measure the radius of curvature in the magnetic field which gives you the mass
Isotope.
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
An Aluminum atom is 26.9815 AMU on *average*.
Most of the mass in an atom is in the nucleus. The protons and neutrons are about the same weight, 1 amu. The elecrtons are 1/1840 of the mass of an proton. Neutrons are 2000 times heavier than electrons and protons have an equal mass of neutrons
Most of the atom's mass is concentrated in the nucleus.
Actually in mass spectrometer the isotopes of an element are separated by applying magnetic field.Each isotope is then compared with carbon-12 to get the atomic mass of that isotope.
A mass spectrometer measures atomic mass by removing one or more electrons from an atom. The spectrometer then sends the atom through a magnetic field. Because of the missing electrons, the atom has more protons than electrons, resulting in a positive charge. The magnetic field bends the path of the positively charged atom as it moves through the field. The amount of bending depends on the atom's mass. The atomic mass of the atom can be calculated from the magnitude of the bend.
Using mass spectrometer, one can identify and/or separate the isotopes of the elements and also predict its composition in a given mixture.
Protons and neutrons= mass
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
To calculate the atomic mass of an element, add up the mass of protons and nuetrons.
To calculate the resolution of a mass spectrometer instrument, divide the mass of the peak by the difference in mass between two peaks. The higher the resolution, the better the instrument can distinguish between different masses.
Aston's mass spectrograph is a magnetic sector mass spectrometer that separates ions based on their mass-to-charge ratio using magnetic and electric fields. Dempster's mass spectrometer is an early design of a mass spectrometer that used electric and magnetic fields to separate ions based on their mass-to-charge ratio. Aston's design was an improvement over Dempster's, offering higher resolution and precision in analyzing isotopic composition.
Indium can be ionized in a mass spectrometer using an ionization source such as electrospray ionization (ESI) or inductively coupled plasma (ICP) ionization. These sources generate ions from the indium sample, which are then analyzed in the mass spectrometer for determination of elemental composition or isotopic ratios.
A mass spectrometer is a device used to determine atomic masses by separating and measuring the mass-to-charge ratio of ions. By analyzing the deflection of ions in a magnetic or electric field, the mass spectrometer can provide accurate measurements of atomic masses.
To calculate the mass of an atom, you can add up the masses of its protons, neutrons, and electrons. Protons and neutrons have a mass of about 1 atomic mass unit each, while electrons have a much smaller mass that can usually be ignored. The total mass of an atom is usually given in atomic mass units (amu).
The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.
