Nitrogen is unreactive at room temperature but becomes reactive at elevated temperatures (on heating) or in the presence of catalysts. In nitrogen molecules, there is extensive delocalization of electrons.
In crystal lattice, size of the cation is larger in a tetrahedral hole than in an octahedral hole. The cations occupy more space than anions in crystal packing.
Electrons are ejected from a certain metal when either blue or violet light strikes the metal surface. However, only violet light causes electron ejection from a second metal. The electrons in the first metal require less energy for ejection.
