There are a few ways to determine the mass number, depending on what information you have about the isotope:
1. The mass number is calculated as the sum of an isotope's protons and neutrons.
2. The name of an isotope generally includes the mass number. For instance, carbon-14 has a mass number of 14.
3. The atomic mass (aka isotope mass or atomic weight) rounded to the nearest whole number is the mass number.
The Atomic Mass number is calculated by summing the number of protons and neutrons in an atom's nucleus. This number is an average of all the isotopes of an element, weighted by their relative abundance on Earth. The atomic mass is typically given in atomic mass units (amu).
The atomic mass of an atom is the sum of the protons and neutrons present.
the mass number is equal to the number of Neutrons plus the number of Protons mass# = #n + #p

What does the formula atomic mass minus the atomic number equal?
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
Can the number of neutrons in the nucleus be calculated by subtracting the atomic number from the mass number?
Yes, the number of neutrons in the nucleus can be calculated by subtracting the atomic number from the mass number. The mass number represents the total number of protons and neutrons in the nucleus, so by subtracting the atomic number (number of protons), you can determine the number of neutrons.
How is the number of neutrons in an atom found?
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.
What is the atomic mass number of an isotope that has an atomic number of 5 and includes 6 neutrons?
The atomic mass number is calculated by adding the number of protons and neutrons in the nucleus. In this case, the isotope with atomic number 5 and 6 neutrons would have an atomic mass number of 11 (5 protons + 6 neutrons = 11 atomic mass number).
Protons are the same as the mass or the atomic?
The atomic number is the number of protons. For example, the atomic number of Hydrogen is 1, because it has 1 proton. The mass is calculated using protons, neutrons, and electrons.
What does the formula atomic mass minus the atomic number equal?
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
The number of neutrons in the nucleus of an atom can be calculated by what?
The number of neutrons in the nucleus of an atom can be calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom. Atomic mass - Atomic number = Number of neutrons.
How is the atomic mass calculated for neon?
Neon is a non meta element. Atomic mass of it is 20. Atomic number of it is 10.
Can the number of neutrons in the nucleus be calculated by subtracting the atomic number from the mass number?
Yes, the number of neutrons in the nucleus can be calculated by subtracting the atomic number from the mass number. The mass number represents the total number of protons and neutrons in the nucleus, so by subtracting the atomic number (number of protons), you can determine the number of neutrons.
How is the number of neutrons in an atom found?
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.
What is the atomic mass number of an isotope that has an atomic number of 5 and includes 6 neutrons?
The atomic mass number is calculated by adding the number of protons and neutrons in the nucleus. In this case, the isotope with atomic number 5 and 6 neutrons would have an atomic mass number of 11 (5 protons + 6 neutrons = 11 atomic mass number).
How can the number of protons electrons and neutrons be calculated when giving the mass number?
To calculate the number of protons, electrons, and neutrons based on the mass number: The number of protons is equal to the atomic number of the element. The number of electrons is also equal to the number of protons in a neutral atom. The number of neutrons can be calculated by subtracting the number of protons (atomic number) from the mass number.
Protons are the same as the mass or the atomic?
The atomic number is the number of protons. For example, the atomic number of Hydrogen is 1, because it has 1 proton. The mass is calculated using protons, neutrons, and electrons.
What determines the atomicity of the elements?
The Atomic Mass number tells the atomic mass of an element. The mass is calculated as the mass of all the protons and neutrons in the center of an atom.
Neutrons in the nucleus of an atom calculated?
Mass number minus atomic number = number of neutrons
What you the mass number of H2o?
The mass number of water (H2O) is calculated by summing the atomic masses of its components. Hydrogen has an atomic mass of 1 and oxygen has an atomic mass of 16. Therefore, the mass number of water is 18.
How do you tell how many neutrons are in an atom with the atomic number of 12?
To find the number of neutrons in an atom with an atomic number of 12 (which is the number of protons), you would subtract the atomic number from the atomic mass number. The atomic mass number is the sum of the protons and neutrons in the atom. For an atom with an atomic number of 12, the number of neutrons can be calculated by subtracting 12 from the atomic mass number given for that specific atom.
