Can a physical quantity have direction and still be a scalar?

Yes, a physical quantity can have magnitude and direction but still be a scalar if it doesn't obey the vector addition. An example is Electric Current which has magnitude and a fixed direction, but it does not follow vector laws of addition.

Answer the following:

 (i) Transition elements form interstitial compounds.

(ii) Mns+(3d4) is strongly oxidising, whereas Cr2+(3d4) is strongly reducing.

(iii) Transition metals have high melting...

II)Cr2+ is reducing agent as its configuration changes from d4 to d3, when it is oxidized to Cr3+ .The d3 configuration have a half-filled t2g level which is very stable. On the other hand, the reduction of Mn3+ to Mn2+ results in the half-filled (d5) configuration which has extra stability hence Mn3+ acts as oxidizing agent.
