Electronic, ionic and permanent

Electronic and ionic

Electronic only

True

False

Resistivity of Ni will decrease at all temperatures because Cu is a better conductor than Ni

Resistivity of Ni remains the same

Resistivity of Ni will increase at all temperatures as Cu destroys the periodicity of Ni and acts as defects

Residual resistivity of Ni at low temperature will increase as Cu atoms act as defect centres

Are shared only between neighbouring atoms
