(A) C(Graphite) ----- Â Â 4.NETWORK
COVALENTÂ Â ( among the 4 valancy electrons 3 are making
sigma bonds with neighbouring C atoms leeds to covalent
structure.)
(B)
N2Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
------Â Â 5.MOLECULAR ( since there are only molecular
interactions between N2 molecules)
(C)
Kr              Â
------Â Â 1. ATOMIC ( since it is an inert gas )
(D)
Au             Â
------Â Â Â 2.METALLICÂ Â Â Â ( since
gold is a metal there is metallic bond between two Au atoms)
(E)
MgBr2Â Â Â Â Â Â Â Â
------Â Â Â 3.IONICÂ Â ( since there is ionic
bond between s-block element(metal) & p-block element(Br) )
