It is convenient to describe the composition of an atom in terms of the number of protons and neutrons in its nucleus (Figure 1 ). The term atomic number , conventionally denoted by the symbol Z , indicates number of protons present in the nucleus of an atom, which is also equal to ...
Fm (Fermium) has an atomic number 𝑍=100Z=100 and, thus, 100 electrons as a neutral atom (spectrum Fm I); Fm C is the H-like ion in which a single electron stays with the nucleus after 99 electrons have been removed (ionised). The above relations point to a density of 3 × ...
