Write the full electron configuration of Mg. Write the valence orbital diagram corresponding to the ground state of Nb, whose configuration is (Kr) 4d^4 5s^1. Give the orbital diagram for an atom of oxygen. Writ
The electrochemical impedance spectroscopy (EIS) diagram in Supplementary Fig. 23 shows smaller impedance of Mg–N–C as comparing to Pt/C. According to the rotating ring disk electrode (RRDE) test result shown in Fig. 4c, the electron-transfer rate for Mg–N–C is close to 4, similar ...

These changes in chemical composition, which can be explained by the alloy's phase diagram, along with the observed change in porosity level demonstrate that the occurrence of swelling in the cube sintered at 595 °C can be originated from pulling out of the liquid phase formed in near-...
(a) Reverse pole diagram before deformation; (b) SEM image near the region of twin nucleation with two twins nucleated at almost the same time; (c,d) SEM and EBSD images of the grown twins. In the small grain size sample in Fig. 6, dozens of grains sit in front of the notch, ...
(c) What is the electron configuration of an electrically neutral atom of oxygen?An atom easily loses two electrons to form the ion R^2+. The element, which is in Period 6, forms the oxides RO and RO2. Give the orbital diagram...
The origins of the electronic conductivity observed can be related to: (i) the existence of intrinsic defects, e.g., Mg, Sc, or Se vacancies, or (ii) the presence of undesired electron conducting secondary phases in the as-prepared MgSc2Se4 sample. The 25Mg NMR results do not indicate...
