    The section below provides more detailed description of these topics, worked examples, and practice problems. Recognize that elements are identified by the number of protons, but the number of neutrons may vary (isotopes). Calculate natural abundance and atomic mass from mass spectrometry data.

    Jan 9, 2018 · The reason increasing atomic number doesn't always equate to increasing mass is because many atoms don't have the same number of neutrons and protons. In other words, several isotopes of an element may exist.

    Sep 28, 2022 · For this reason, the sum of an atom’s protons and neutrons is known as its mass number (A). Carbon, for example, can have a mass number of 12, 13, or 14 (six protons and six, seven, or eight neutrons), and hydrogen can have a mass number of 1, 2, or 3 (one proton and zero, one, or two neutrons).

    Aug 29, 2023 · The vertical scale is related to the current received by the chart recorder - and so to the number of ions arriving at the detector: the greater the current, the more abundant the ion. As you will see from the diagram, the commonest ion has a mass/charge ratio of 98.

    The average atomic mass of an element is a weighted average calculated by multiplying the relative abundances of the element's isotopes by their atomic masses and then summing the products. The relative abundance of each isotope can be determined using mass spectrometry.
