The telluride ion
. It is the final stable member of the series of dianions O2−
, and Se2−
Tellurides also describe a class of compounds formally derived from Te2−; i.e., their electronic structure is reasonably well approximated by considering the tellurium atom as having an octet configuration. Using this approach, Ag2Te is derived from Ag+.
See Tellurides for a list.
In aqueous solution
exists only at high pH. In neutral conditions, hydrogen telluride
, is prevalent. In acid conditions, hydrogen telluride
Te, forms. Products of three reaction products with tellurium have economic importance: cadmium, bismuth and lead. Cadmium telluride has photovoltaic acitivity, while bismuth and lead tellurides are exceptional thermoelectric materials.
