In general oxidation is defined as gain of oxygen or loss of electron or hydrogen by an atom. Reduction is defined as gain of electron or hydrogen or loss of oxygen by an atom.
In a balanced redox reaction we have two half reactions
a) reduction half reaction : the oxidation number of element decreases
b) oxidation half reaction : the oxidation number of element increases

The element undergoing reduction is Pd.
the oxidation number of Pd decreases from +2 to 0
Thus the reduction half reaction will be

The Pd (II) ion will take two electrons and will give Pd (0)

Answer:
The value of an intensive property may vary with time and its position within the system. Examples of intensive properties include temperature, velocity, mass density, specific volume, and specific energy. An extensive property does not have a value at a point, and its value depends on the extent or size of the system.
