WebbHowever, since the atomic number "Z" can always be determined by the chemical symbol, it is common practice to only state the mass number (e.g., 14 C) and pronounce it as "carbon fourteen." If the letter "m" immediately follows the mass number (e.g., technetium-99m), it indicates a metastable state of the atomic nucleus (i.e., a stable state other than the … WebbAluminum(Al)= 1s^2 2s^2 2p^6 3s^2 3p^1.
