It's the atomic number + the number of neutrons
to find the average atomic mass you must multiply the mass by it's percent natural abundance. do that for each isotope and add your answers together

∙ 13y agoAtomic Mass is the weighted average of the mass of all forms of that element, compared to 1/12 of an atom of carbon-12.
The 'weighted average' bit is responsible for the decimal places in atomic masses, for example Chlorine, Cl occurs as Cl-35 and Cl-37, with abundances of 75% and 25% respectively, so the atomic mass of Chlorine is 35.5

How are atomic mass on the periodic table calculated?
Atomic mass is determined by mass spectrometry.
What is the calculated atomic mass of boron?
10.81
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.
How was atomic mass first calculated?
The atomic mass is determined by accurate mass spectrometry. If you think to atomic weight, 200 years ago, this parameter was related to hydrogen with a given atomic weight of 1.
What is a protons mass calculated by?
They are calculated by atomic mass units (amu) proton-1amu neutron-1amu electron-0amu
How are atomic mass on the periodic table calculated?
Atomic mass is determined by mass spectrometry.
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.
What is the calculated atomic mass of boron?
10.81
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.
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.

The atomic mass is determined by accurate mass spectrometry. If you think to atomic weight, 200 years ago, this parameter was related to hydrogen with a given atomic weight of 1.
What is a protons mass calculated by?
They are calculated by atomic mass units (amu) proton-1amu neutron-1amu electron-0amu
How is the number of neutrons in an atom found?
The number of neutrons can be calculated if the atomic number and mass number of an element is known. The number of neutrons = Mass number - atomic number.
What is the difference in molar mass and atomic mass?
molar mass is the actual mass of the one atom but relative mass is the average isotopes of the atoms.------------------------------------------Atomic mass is the mass of an isotope, expressed in atomic mass units.Molar mass is the mass of molecule, calculated from the atomic weights of the contained chemical atoms, expressed in grams.
What best describes the weight average of atomic mass on an element?
The atomic weight (not mass) of a chemical element is calculated considering the percentage concentatration of natural isotopes and the atomic mass (not weight) of each isotope.
Average atomic mass of an element?
"The average atomic weight (not mass) of a chemical element is calculated considering the percentage of each natural isotope and the atomic masses of these isotopes."
Which is smaller titanium or zirconium?
Do you think at atomic radius ? Zr calculated atomic radius: 206 pm, Hf calculated atomic radius: 208 pm. Or atomic mass? Zr: 91,224, Hf: 178,49.
