Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in shells. Which statement correctly describes the average atomic mass of an element? The average mass of an atom is found by averaging over the natural abundances of its isotopes.
The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol. Average atomic mass = f 1 m 1 + f 2 m 2 + … + f n m n where f is the fraction representing the natural abundance of the isotope and m is the mass number (weight) of the isotope. The atomic mass for each element appearing on the periodic table represents the weighted average of masses for each individual isotope of an element. One is 10.013 amu and is 19.9% abundant.

An element key shows you the name of the element, its atomic number, its symbol, and its average atomic mass the technical answer would be average atomic mass is the atomic mass found on. It is a weighed average of the different isotopes of an element. Nmat practice set part 1 & part 2 with answer key. The average atomic mass is simply a way for scientists to account for the stable isotopes of an element this sum represents the weighted average atomic mass of the element. Print answer key pdf take now schedule copy. The atomic mass is an experimental number determined from all of the naturally occuring isotopes when these are averaged together you get the average atomic mass shown on the periodic table so the answer can only be precise out to the least precise or most uncertain place, hundredths place. Want to see this answer and more? Okay, so, looking at average atomic mass of atoms of an element ah, this this is calculated pretty much the same as he would calculate your gps. Then, calculate the average atomic mass by considering the mass and abundance of each isotope. Taking chlorine as an example, you will find. In the average atomic mass gizmo, you will learn how to find the average mass of an element using an instrument called a mass spectrometer. The final calculate step should serve as an answer key for the student, based upon the combination of isotopes, mass, and abundancies that they chose.
