Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). WebThe identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes.

WebHowever, 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 …

WebIt is represented with the letter ‘Z.’ All the atoms of a particular element have the same number of protons, and hence the same atomic number.
