The symbols for several common elements and their atoms are listed in Table 2.3.2 2.3. 2. Some symbols are derived from the common name of the element; others are abbreviations of the name in another language. Symbols have one or two letters, for example, H for hydrogen and Cl for chlorine.

Learning Objectives. By the end of this section, you will be able to: Write and interpret symbols that depict the atomic number, mass number, and charge of an atom or ion. Define the atomic mass unit and average atomic mass. The development of modern atomic theory revealed much about the inner structure of atoms.
Write and interpret symbols that depict the atomic number, mass number, and charge of an atom or ion. Define the atomic mass unit and average atomic mass. Calculate average atomic mass and isotopic abundance. The development of modern atomic theory revealed much about the inner structure of atoms.
An atomic symbol consists of three parts represented as: The mass number is the sum of the number of neutrons and protons. Atomic number is the number of protons. The electrical charge represents the net gain (for anions) or loss (for cations) of electrons. X represents the alphabetical symbol.
