HERE IS YOUR ANSWERS

                                                                                                                                   

(A.1) Titanium is called strategic metal as it can be use in producing space craft , aircraft and missiles. It is the fourth most abundant metal on the earth. Since it is resistant to salt water and acid corrosin it is used in making durable corrosion resistant alloys.

                                                                                                                                 

(A.2) Non metal has the tendency for gaining the electrons. ... The nonmetals i.e. F, O, Cl has the tendency for gaining the electrons. They do not get the proton that means the positively charged ion. On the other hand, metals lose the valence electrons to form the cations to get the completely stable octet.

                                                                                                                                           

(A.3) Aluminum is more reactive than iron but it doesn't corrode It is because of aluminium oxide layer. Aluminium outer surface layer is oxidized whenever it came in contact with the air and so result in aluminium oxide layer which is resistive in nature and remain attached to it.
