The reason for using the element of group 0 configuration is considering the full electron configuration becomes very long for atoms with high atomic numbers. 1 See answer Advertisement Advertisement Globug9946 is waiting for your help. Strontium is atomic number 38 so its electron configuration can be written: 2.8.18.8.2. Wiki User. The unit Cells repeats itself in three dimensional space to form the structure. Accordingly, the combined first three ionization energies of aluminium are far lower than the fourth ionization energy alone.

In the space below, write the Noble Gas (abbreviated) electron configurations of the . Can you explain this answer? Why are you allowed to use the coarse adjustment when you focus the low power objective lens? Abbreviated electron configuration is also called noble gas configuration or condensed electron configuration. What is the Noble-gas configuration for Strontium? The configuration that corresponds to the lowest electronic energy is called the ground state.
