The band model of solids is an extended of the molecular orbital (MO) method. The overlap of atomic orbitals in an extended solid produces rise to continuous bands of electronic energy levels associated with different degrees of bonding. In a simple monatomic solid the bottom of the band is build up of orbitals bonding between all neighboring atoms; orbitals at the top of the band are antibonding, and levels in the middle have an intermediate bonding character. Different atomic orbitals may, in principle, give rise to different bands, although they may overlap in energy.

What was the calculated ?H value obtained for the reaction NH3 + HCl –› NH4Cl using the thermodynamic data in your lab procedure? The thermodynamic data is: •?H°f for NH3 (aq) = -
Q. Define the Normality of solutions? Ans. Sometime normality is used to measure concentration. Normality (abbreviated N) is the number of gram-equivalent masses of solute in 1
