What is the valency of promethium?
Promethium is an element and does not have a charge. As it has only be found in trace quantities, its chemistry has not been fully investigated. It has been anticipated that the likely charge when it forms compounds would be +3.
What is latest definition of organic chemistry?
This is the chemistry of compounds containing carbon; but traditionally compounds containing carbon are considered as inorganic compounds.
What element forms more compounds than any other element and compounds containing it are called organic compounds?
uranis has the most compounds
An inorganic compound containing one atom of phosphorous and three atoms of oxygen in the form of the ion?
There are none. The phosphite ion PO33- ion is theoretical. When you try to form compounds containing it you actually get HPO32- where the H atom is bonded directly to phosphorus. Historically these compounds are confusingly called phosphites, and the modern name is phosphonate.
A compound containing iron?
FeCl2, FeS, and FeSO4 are three common compounds containing iron.

List three common compounds containing hydrogen?
Water, ethanol, and octane (a constituent of most gasoline).
What are the physical and chemical properties of promethium?
After the Pauling electronegativity (1,13) promethium is a reactive metal but the chemistry of Pm is only superficially known.The valence of ions in solution is +3. Promethium compounds known: halides, oxides, nitrates, sulfates, hydroxides etc.
What compounds containing carbon?
Every single organic thing contains carbon.
Is biochemistry the study of carbon containing compounds?
No.... organic Chemistry is the study of carbon containing compounds.
What are compounds containing no carbon called?
they are called inorganic compounds
Compounds containing carbon found in living things?
Carbon containing compounds found in living things are called organic compounds. Examples of organic compounds are carbohydrates, proteins, lipids and nucleotides.
Compounds that contain carbon are called what?
Compounds containing carbon are referred to as organic compounds
