Interchalcogen

<p>The <a href="/facts/Chalcogen/nXLGmnqL">chalcogens</a> react with each other to form interchalcogen compounds.
</p><p>Although no chalcogen is extremely <a href="/facts/Electropositivity/H7Vq7Uah">electropositive</a>, nor quite as <a href="/facts/Electronegativity/H7Vq7Uah">electronegative</a> as the <a href="/facts/Halogen/YeFgWHeA">halogen</a> <a href="/facts/Fluorine/YUV0Fb8m">fluorine</a> (the most electronegative element), there is a large difference in electronegativity between the top (<a href="/facts/Oxygen/acyn6o8r">oxygen</a> = 3.44 — the second most electronegative element after fluorine) and bottom (<a href="/facts/Polonium/G4rzsyjP">polonium</a> = 2.0) of the group. Combined with the fact that there is a significant trend towards increasing metallic behaviour while descending the group (oxygen is a <a href="/facts/Gas/hVVAoodV">gaseous</a> <a href="/facts/Nonmetal_(chemistry)/0oejKuzK">nonmetal</a>, while polonium is a silvery <a href="/facts/Post-transition_metal/wjp3aeGn">post-transition metal</a>), this causes the interchalcogens to display many different kinds of bonding: <a href="/facts/Covalent/EzMLf3Pz">covalent</a>, <a href="/facts/Ionic_bond/R6nUJI5u">ionic</a>, <a href="/facts/Metallic_bonding/Ht958du4">metallic</a>, and <a href="/facts/Semimetal/ELtXVlI5">semimetallic</a>.
