What is the temperature of the heated gas? [12] As an infrared detector, PbS functions as a photon detector, responding directly to the photons of radiation, as opposed to thermal detectors, which respond to a change in detector element temperature caused by the radiation. Associate whatever element(s) is attached to the group ion and name accordingly. The mass (in grams) of a compound is equal to its molarity (in moles) multiply its molar mass: grams = mole × molar mass. These metals can have more than one charge or oxidation state. Molecular Formula. how come it is not lead (II) sulfide? Name the following compounds: NaF sodium fluoride. Addition of hydrogen sulfide or sulfide salts to a solution containing a lead salt, such as PbCl2, gives a black precipitate of lead sulfide. Although of little commercial value, PbS is one of the oldest and most common detection element materials in various infrared detectors. PbS2 or H4PbS2. Synonyms. If the element comes in front of the ion group, the name of the element is simply added to the beginning of the compound name. It is a semiconducting material with niche uses.
