Specifications: Protactinium Protactinium is a chemical element with the symbol Pa and atomic number 91. Protactinium is a silver metallic element that belongs to the actinide group, with a bright metallic luster that it retains for some time in the air. It is superconductive at temperatures below 1.4 K.
The universe is compromised of many elements, each one relying on the other to properly function in the world. Protactinium is a chemical element found on the Periodic Table of Elements. This chemical is represented on the table by the letters Pa, with a heavy atomic weight and number of 91.
Protactinium is a silver and metallic element that has a high luster to it. It is an element that is present in air, and gives a high radioactive charge. Due to this elements rarity and toxicity to humans, it is used solely for scientific research. There are superconductive elements that are also present in this chemical once it falls under a temperature of 1.4 K.
Protactinium is an element that was discovered in the late 1800s. It was seen as an element that existed between uranium and thorium. At the time, scientist Mendeleev discarded this finding as erroneous information. It was not until several years later was it discovered that this element that existed between the two chemical compounds was protactinium.
