Each element on the periodic table has an atomic mass -- an approximation of the mass of a single atom of that element. Because atoms are so small, a specific unit is used to measure the mass of small quantities of atoms. Very large quantities of atoms a
To calculate the atomic mass of asingle atomof an element, add up the mass ofprotons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons. The...
Hence, the atomic mass is the sum of its protons and neutrons, which will be 12; therefore, 12u is the atomic mass of Carbon. Problem Sum to Calculate Atomic Mass Calculate the atomic mass of an element with an atomic number of 18 and a neutron number of 20. Solution: The number of...

How do you calculate atomic mass from atomic number? What is relative atomic number? Why would the atomic number be better to identify an element than the atomic mass? How are atomic numbers and mass numbers written? What is counted in an atom to determine mass number?
To calculate the atomic mass of element R, we can use the following formula, which takes into account the masses and relative abundances of the isotopes: Atomic Mass=(m1×f1)+(m2×f2)+(m3×f3) Where: m1,m2,m3 are the masses of the isotopes, f1,f2,f3 are their respective...
