Explanation:
non-metals are those elements which do not possess properties of metals i.e. participation in ionic reactions, formation of anions, oxides, acids, etc.
they are present in the p-block of periodic table i.e., after the 13th group.
Sulfur is a non-metal
Its basic physical properties are-
symbol-S
atomic no.-16
atomic mass-32
it is bright yellow, crystalline solid at room temperature
It is present in the 16th group of periodic table also called as chalcogen
It is multivalent i.e. can possess more than one valencies
it also has catenation property
sulfur atoms form cyclic octatomic molecules with a chemical formula S₈ and forms a crown shaped structure.
Sulfur is often found on Earth near the edges of volcanoes and hot springs
hydrogen sulfide has a rotten egg smell (really really bad one)
actual sulfur is odourless
