The Atomic Mass of an element is primarily determined by the number of protons and neutrons in the nucleus of its atoms, collectively known as nucleons. Protons contribute a positive charge and a mass of approximately 1 atomic mass unit (amu), while neutrons contribute a similar mass but no charge. The atomic mass unit is a weighted average of all the isotopes of an element, reflecting both their mass and natural abundance. Electrons have negligible mass and do not significantly affect the atomic mass.

What two factors determine the atomic mass of an elements?
neutrons and protons
What does one determine an atoms atomic mass?
If you mean "how does one determine an atoms atomic mass?", then the answer would be to find a periodic table of elements where the whole numbers indicate atomic number and the other indicating atomic mass. Atomic number is generally described as the number of protons in a naturally occurring atom of a given element, and the atomic mass is the number of protons + number of neutrons in an atom.
How do scientists determine the number of neutrons and isotopes in an atom?
Atomic mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
What information could you use to determine the atomic number of unknown element that has a mass number of 22?
To determine the atomic number of an element with a mass number of 22, you would need the number of protons in the nucleus. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons (mass number) from the mass number gives you the number of protons (atomic number).
What is an atomic mass number?
Atomic mass and atomic number are two different things. Atomic mass is the mass of an atom compared to that of hydrogen. The atomic number is the atom's position in the periodic table. It's also the number of protons it has.
What two factors determine the atomic mass of an elements?
neutrons and protons
How you can determine the number of protons electrons and neutrons an atom has from an atom's mass number and its atomic number?
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
What are counted in an an atom to determine mass number?
Atomic Mass: protons AND neutrons atomic number: just protons
What does a mass number determine?
mass number = number of protons + number of neutrons DIFFERENT FROM ATOMIC MASS atomic mass = weighted average of all the isotopes of that element

To determine the number of neutrons in an atom, what must be done?
To determine the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the atom). Neutrons are particles found in the nucleus of an atom and carry no charge.
How do you determine neutrons in element?
subtract the atomic number from the mass number
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
What part of the nucleus determine the atomic mass for an element?
All parts of the nucleus, protons and neutrons if any, contribute to the atomic mass. The total number of protons and neutrons in an atom is its isotope mass number.
