WebSee more Lanthanum products. Lanthanum (atomic symbol: La, atomic number: 57) is a Block F, Group 3, Period 6 element with an atomic weight of 138.90547. The number of electrons in each of lanthanum's shells is [2, 8, 18, 18, 9, 2] and its electron configuration is [Xe] 5d 1 6s 2. The lanthanum atom has a radius of 187 pm and a Van der Waals ... WebAug 12, 2015 · A mischmetal, also known as cerium mischmetal, is an alloy of rare earth elements, namely those from the lanthanum series. The resultant mischmetal by itself is too soft to use as a flint, such as used in a lighter. Therefore, it is blended with iron oxide and magnesium oxide. The resulting man-made material is called ferrocerium — probably ...
