>> I believe, its not "hybridation", but "hybridization". And I think, by your question, you meant "What is sp hybridization? (or sp2 hybridization or sp3 hybridization)" (with small s and small p)... Well, I have attached a link to this answer that should help you understand hybridization.
whats the bond angle P and S?
>> This question cannot be answered if you do not provide any further information. Mostly, you will find that the bond angle will depend on which hybridization it is (sp, sp2 or sp3) and how many bonds there are and if there is any other kind of bond etc.
