i) Reactivity with
pes where E = S, Se, Te or Po. Ozone (O,) a
and
ide (SO2) are gases while selenium dioxide (SeO,) is solid.
Reducing property of dioxide decreases from SO, to Te0,;(SO, is
reducing while TeO, is an oxidising agent Besides EO, type.
sulphur, selenium and tellurium also form EO, type oxides (SO,,
SeO3, TeO3). Both types of oxides are acidic in nature.)
uards the halogens: Elements of Group 16 for-
L is
an element of the group and X is a halogen. The stability of the
halides decreases in the order F> CI> Br >I. Amongst hexahalides,
hexafluorides are the only stable halides. All hexafluorides are
large number or na
000US in nature. They have octahedral structure. Sulphur
