To find the number of neutrons in an atom, you subtract the atomic number from the mass number. A neutral atom contains the same number of electrons as protons. What is the difference between atomic mass and atomic number? The atomic number of an element can be determined by considering the number of protons in its atoms.

What is the difference between an isotope and an ion? Isotope: neutral atoms of same element with different masses. Ion: atoms that have gained/lost electrons and become charged. Given that chlorine is 75% Cl-35 and 25% Cl-37, calculate the average atomic mass of chlorine. (35)(0.75) + (37)(0.25) = average atomic mass of chlorine

C) The relative atomic mass of carbon is 12.01 amu because carbon-12 is the most abundant isotope, with smaller amounts of carbon-13 and carbon-14. D) The terms “mass number” and “relative atomic mass” can be used interchangeably. E) Mass spectrometry is used to find the mass of each isotope of an element, and measure their abundance.

Oct 03, 2014 · The weighted average atomic mass is calculated by multiplying the decimal equivalent of each isotope times its mass and adding up all the results for all the naturally occurring isotopes. AMU = atomic mass unit = mass of one proton = mass of one neutron. Example: A sample of Cesium, Cs, has the following % abundance: Cs-132 = 20.0%; Cs – 133 ...
