Potassium 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, Potassium metal is also represented by the symbol K. This atomic symbol of Potassium is useful in indicating the position of metal K in the periodic table. If you are curious-headed or a science-geek, the common questions about metals are What is Potassium? What are its physical, chemical, mechanical, electrical and thermal properties? Find all the relevant facts about K metals in the following sections.

Periodic Table of Potassium

Periodic table of Potassium 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. Potassium metal belongs to Alkali Metals 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 1, whereas its period number is 4. It is placed under s block of the periodic table & is one of the prominent s block elements.

Potassium Metal Properties

Metals have certain properties by which they can be distinguished from one another. Magnetic and Atomic Structure of Potassium 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 Potassium is 19 and its atomic weight is 39.10 amu. The electrons in its atom are arranged in orbitals as [Ar] 4s1. Nuclear particles in Potassium atom are 20 neutrons, 19 protons and 19 electrons.

Physical and Chemical Characteristics of Potassium

Physical and chemical characteristics of Potassium are two major criteria while comparing this metal with other metals. Physical Properties of Potassium 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 Silvery Gray Solid. It starts melting at 63.65 °C. All these Potassium metal properties together define what is Potassium?
