Answer:
conductivity of metals decrease with increase in temperature because
(1) In metals a large number of outermost electrons of atoms occupy conduction bands.
(2) Band formation in metals results in delocalisation of outermost electrons forming metal ions or cations.
(3) The metallic cations occupying crystal lattice sites vibrate about mean positions.
4) As temperature increases the vibrational motion increases which interrupts flow of electrons decreasing electrical conductivity.
