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.

How do you you find the mass number of an atom?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is used to find the mass of an atom?
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
What has a different mass number than the normal atom?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you find the molar mass of an atom?
Molar mass is a term applied for molecules, not for atoms.
What Used to find the number of neutrons?
To find the number of neutrons in an atom you subtract the atomic mass fromthe mass number

What is used to find the mass of an atom?
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
What is the number of an atom with 5 protons and 7 neutrons?
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
What has a different mass number than the normal atom?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you find the molar mass of an atom?
Molar mass is a term applied for molecules, not for atoms.
What does the mass number of an atom help you find?
it helps you find where the nucleus is located
Why it is not possible to find the absolute mass of an atom?
It is the smallest particle
What Used to find the number of neutrons?
To find the number of neutrons in an atom you subtract the atomic mass fromthe mass number
How do you find atomic mass and mass number of isotope?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How many electrons does an atom has?
It depends on the atom you are reffering to, but to find the electrons take away the number of protons from the mass number of the atom.
What is the difference in mass of Na ion and Na atom?
The difference in mass between a sodium atom and a sodium ion (supposing Na+) is 9.10938188 × 10-31kg (the mass of an electron). This is due to the sodium atom losing an electron to form an ion. In order to attain the mass of a single sodium atom you need to divide the molar massn (mass number) of sodium by avogadro's number. You can then find the mass of the ion by subtracting the mass of an electron from the mass of a sodium atom.
How do you find out the mass of an atom?
By the addition of the number of protons and the number of electrons
