Protactinium ( /ˌproʊtækˈtɪniəm/ PROH-tak-TIN-ee-əm) is a chemical element with the symbol Pa and atomic number 91. It is a dense, silvery-gray metal which readily reacts with oxygen, water vapor and inorganic acids.
Protactinium. The name comes from the Greek words "protos" meaning first, and "actinium" which are the parent elements of protactinium in the decay chain.
Protactinium is paramagnetic.
Protactinium is not corrosive.
Nothing is made from protactinium.
yes, protactinium is a metal
Protactinium is a highly reactive metal and it can react with water, particularly in its radioactive forms. This reaction can release hydrogen gas and produce protactinium hydroxide. However, protactinium is rare and not often encountered in everyday situations.
Protactinium is a natural chemical element; but protactinium can be obtained artificially by nuclear reactions from 232Th.
Valences of protactinium are: 2, 4,5.

Protactinium is a member of the actinoids series.
Protactinium is a very rare, very poisonous and very expensive element present in certain uranium ores and only in very minuscule amounts. Assigned Atomic number is 91 and it is in class: Metal. Protactinium has no known uses other than for scientific research and would certainly not be wasted on a chicken.
The chemical symbol for Protactinium is Pa.
