Related Elements

Elemental PotassiumSee more Potassium products. Potassium (atomic symbol: K, atomic number: 19) is a Block S, Group 1, Period 4 element with an atomic weight of 39.0983. The number of electrons in each of Potassium's shells is [2, 8, 8, 1] and its electron configuration is [Ar] 4s1. The potassium atom has a radius of 227.2 pm and a Van der Waals radius of 275 pm. Potassium was discovered and first isolated by Sir Humphrey Davy in 1807. Potassium is the seventh most abundant element on earth. It is one of the most reactive and electropositive of all metals and rapidly oxidizes. As with other alkali metals, potassium decomposes in water with the evolution of hydrogen because of its reacts violently with water, it only occurs in nature in ionic salts.Potassium Bohr Model In its elemental form, potassium has a silvery gray metallic appearance, but its compounds (such as potassium hydroxide) are more frequently used in industrial and chemical applications. The origin of the element's name comes from the English word 'potash,' meaning pot ashes, and the Arabic word qali, which means alkali. The symbol K originates from the Latin word kalium.

Vanadium Bohr ModelThe number of electrons in each of Vanadium's shells is 2, 8, 11, 2 and its electron configuration is [Ar] 3d3 4s2. The vanadium atom has a radius of 134 pm and a Van der Waals radius of 179 pm. Vanadium was discovered by Andres Manuel del Rio in 1801 and first isolated by Nils Gabriel Sefström in 1830. In its elemental form, vanadium has a bluish-silver appearance. Elemental VanadiumIt is a hard, ductile transition metal that is primarily used as a steel additive and in alloys such as Titanium-6AL-4V, which is composed of titanium, aluminum, and vanadium and is the most common titanium alloy commercially produced. Vanadium is found in fossil fuel deposits and 65 different minerals. Vanadium is not found free in naturehowever, once isolated it forms an oxide layer that stabilizes the free metal against further oxidation. Vanadium was named after the word "Vanadis" meaning goddess of beauty in Scandinavian mythology.
