Praseodymium Metal

Metals have been an inseparable component of major civilizations since centuries. Although metals were utilized since time unknown, researchers put considerable efforts in giving them appropriate names and defining their different properties and characteristics. This nomenclature process helped in arranging these metals in a well-organized fashion, known as the periodic table. In this periodic table, Praseodymium metal is also represented by the symbol Pr. This atomic symbol of Praseodymium is useful in indicating the position of metal Pr in the periodic table. If you are curious-headed or a science-geek, the common questions about metals are What is Praseodymium? What are its physical, chemical, mechanical, electrical and thermal properties? Find all the relevant facts about Pr metals in the following sections.

Periodic Table of Praseodymium

Periodic table of Praseodymium comments over its position in the periodic table, on the basis of parameters like group number, period row, atomic number and orbital block. The metals which have electrons falling in the same sub-shell are grouped under the same block corresponding to its respective orbital. Praseodymium metal belongs to Lanthanide Series category of the periodic table. Metals down a group have same valency while metals across a period have the same number of shells. Its group number (column number) is Not Available, whereas its period number is 6. It is placed under f block of the periodic table & is one of the prominent f block elements.

Praseodymium Metal Properties

Metals have certain properties by which they can be distinguished from one another. Magnetic and Atomic Structure of Praseodymium are few widely searched properties. Using the comparison facility, you can not only view the individual metal properties, but also compare the properties of multiple metals to get a thorough comparative analysis between the metals of your choice. Atomic number is a basic building block for the arrangement of metals in the periodic table. Atomic number of Praseodymium is 59 and its atomic weight is 140.91 amu. The electrons in its atom are arranged in orbitals as [Xe] 4f3 6s2. Nuclear particles in Praseodymium atom are 82 neutrons, 59 protons and 59 electrons.

Physical and Chemical Characteristics of Praseodymium

Physical and chemical characteristics of Praseodymium are two major criteria while comparing this metal with other metals. Physical Properties of Praseodymium include its external appearance, shininess at surface, color, etc. Properties like density, viscosity, melting and boiling point are also covered in this section. At room temperature, this metal is a Grayish White Solid. It starts melting at 935.00 °C. All these Praseodymium metal properties together define what is Praseodymium?
