Phosphorus, ground-state electron configuration

Use the aufbau principle to write the condensed ground state electron configurations for nitrogen, phosphorus, and arsenic. 

Which of the following is the correct ground state electronic configuration for the 15 electrons of phosphorus, P ... 

Write out the ground state electronic configurations for (a) phosphorus, (b) sodium, and (c) titanium. You can find the atomic numbers of these elements on a periodic table. 

Write the ground-state electron configuration for phosphorus (P). 

Which of the following is the correct orbital diagram for the ground-state electron configuration of phosphorus Explain what is wrong with each of the others. 

In the ground state, phosphorus has the electronic configuration [Ne]3s 3pj3pj,3p with three unpaired electrons this, together with the availability of low-lying vacant 3d orbitals accounts for the predominance of the oxidation states III and V in phosphorus chemistry. 

The thermodynamics of doped a-Si H is a little more complicated, because both the defects and dopants are charged and so interact with the electron distribution whose chemical potential is the Fermi energy. The analysis is for the specific case of n-type doping with phosphorus and, following the model introduced in Chapter 5, it is assumed that both the phosphorus and sUicon atoms may have either three-fold or four-fold coordination. The ground state configuration comprises the four-fold silicon and the three-fold phosphorus, and the defect reaction is,...
