Verified answer
Protactinium is an Actinide element; that is it is radio-active.
Its atomic Number is 91 . Its standard atomic weight is 231
This means it is the 91st element in the Periodic Table, has 91 protons , 91 electrons and (231 - 91) = 141 neutrons.
It is in the 'f-blcck'.
It has seven(7) shells of electrons , with , starting from the inner most shell, 2,8,18,32,20,9,2 electrons in each shell.
Its shortened electron configuration is [Rd] 5f2 , 6d1, 7s2.
It is between Thorium and Uranium in the Periodic Table.
As mentioned above it is radio-active and undergoes decay to Actinium with an alpha particle being emitted.
[231/91]Pa = [4/2]He^(2+) + [227/89]Th
In its nuclear decay its half life is 32760 years.
Its appearance is a bright silvery metallic lustre.
M.P 1841 K . B.P. 4300 K
I'm not too bad at chemistry, but one thing I can't wrap my head around is how perfect the periodic table is. How is it that each element that we know is only one more proton than the last? How come it goes in PERFECT order instead of having a few elements with protons not perfectly linear to the periodic table?
Protactinium is primarily used for research purposes due to its radioactive nature. It is not produced in large quantities and has no significant industrial applications. Some research areas where protactinium is utilized include nuclear reactors and medical imaging.
chemical element with the symbol Pa and atomic number 91
Protactinium is a chemical element with symbol Pa and atomic number 91. Classified as an actinide, Protactinium is a solid at room temperature.
Protactinium is not an important element.
i agree with you!!

1. Protactinium can be separated from uranium ores.
2. Protactinium can be obtained artificially by nuclear reactions, from thorium 232.
Protactinium exist in very low concentrations (ca. 3 mg/kg) in uranium ores.
Does protactinium react with water?
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.
What physical state does protactinium naturally occur in?
At room temperature protactinium is a solid metal.
What odor does protactinium?
Protactinium does not have a distinct odor as it is a radioactive metal that exists primarily in compounds, not in its pure form.
Why is protactinium dangerous?
Protactinium is dangerous due to its radioactivity. It emits high-energy radiation, which can damage cells and tissues in the body, leading to an increased risk of cancer and other health issues. Exposure to protactinium should be minimized to avoid potential health risks.
What is beta decay of thorium 234?
In beta decay of thorium-234, a neutron in the nucleus of thorium-234 is transformed into a proton, releasing an electron (beta particle) and an antineutrino. This process converts the thorium-234 nucleus into protactinium-234.
Is protactinium corrosive?
Protactinium is not corrosive.
Is protactinium magnetic?
Protactinium is paramagnetic.
What is made from protactinium?
Nothing is made from protactinium.
Is protactinium metal?
yes, protactinium is a metal
Does protactinium react with water?
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.
When was protactinium made?
Protactinium is a natural chemical element; but protactinium can be obtained artificially by nuclear reactions from 232Th.
What is protactinium made by?
Protactinium is a natural chemical element; but protactinium can be obtained artificially by nuclear reactions from 232Th.
What group number does protactinium belong to?
Protactinium is a member of the actinoids series.
What is the ionic charge of protactinium?
The ionic charge of protactinium is typically +5.
Is protactinium a gas or a solid?
Protactinium is a solid metal.
When do they use protactinium?
Today protactinium has not practical uses.
Does protactinium have applications in bombs?
Protactinium is not used in bombs.
