Question
The following pictures show the electron population of the bands of MO energy levels of five different materials. Black shading indicates filled orbital; gray shading indicates empty orbital. Which is the correct description of these five? the electrical conductivity of a ceramic superconductor remains high until T_c and then decreases sharply, the conductivity of a semiconductor decreases, and the conductivity of a metal (above T_c) decreases. the electrical conductivity of a ceramic superconductor remains low until T_c and then increases sharply, the conductivity of a semiconductor increases, and the conductivity of a metal (above T_c) decreases. the electrical conductivity of a ceramic superconductor remains high until T_c and then decreases sharply, the conductivity of a semiconductor increases, and the conductivity of a metal (above T_c) increases. the electrical conductivity of a ceramic superconductor remains high until T_c and then decreases sharply, the conductivity of a semiconductor increases, and the conductivity of a metal (above T_c) decreases. The electrical conductivity of a ceramic superconductor remains high until T_c and then increases sharply, the conductivity of a semiconductor increases, and the conductivity of a metal (above T_c) decreases.Explanation / Answer
31) Answer: (e)
Explanation:
Na configuration : [Ne] 3s1
[Ne] means complete bonding orbitals and 3s1 one is the empty orbital. Hence (1) matches.
GaAs : Ga configuration [Ar] 3d10 4s2 4p1
As configuration [Ar] 3d10 4s2 4p3
According to the configuration matches (3).
Diamond: It is the stronger one hence the orbitals are closer to each other.
