Explain the following with suitable examples.(a)12-16 and 13-15 group compounds, (b) Ferromagmetic.

(a)Compounds of 12-16 & 13-15 compounds prepared to acquire a characteristic valence of four and form four bonds as in germanium and silicon. e.g. Of 12-16 compounds are ZnS, CdS, CdSe & HgTe e.g. of 13-15 compounds are InSb, AlP and GaAs.
(b) Ferromagnetic materials exhibit parallel alignment of moments i.e.all unpaired electrons are spinning in parallel direction resulting in large net magnetization even in the absence of a magnetic field. The elements Fe, Ni, and Co and many of their alloys are typical ferromagnetic .
