![]() ![]() South Africa is a leading country which has around 75% of the manganese resources.The hardness of manganese is more than iron, but it is a brittle metal than iron.Magnesium is also required for the human body to perform some metabolic functions.Around 0.1% (by weight) of the earth’s crust consists of manganese element making it the 12th most abundant element in the earth’s crust.According to USGS, around 85 to 90% manganese is used in production of steels.Interesting facts about manganese element are mentioned below. Thus, Manganese has incomplete d-orbitals.Īnd hence, as Manganese has incomplete d-orbitals, it is considered as a transition metal.Īlso see: Location of transition metals on periodic table (Image) 5 Interesting facts about Manganese ![]() In order to have the complete d-orbitals, there must be 10 electrons in it.īut in the ground state electronic configuration of manganese, you can see that it has only 5 electrons in d-orbitals. Protons 25 Neutrons 30 Electrons 25 Symbol Mn Atomic massĢ, 8, 13, 2 Electronic configuration 3d 5 4s 2 Atomic radiusġ97 picometers (van der Waals radius) 1st Ionization energy 7.434 eV ElectronegativityīCC (Body centered cubic) Melting point 1519 K or 1246 ☌ or 2275 ☏ Boiling point 2334 K or 2061 ☌ or 3742 ☏ Density 7.47 g/cm 3 Main isotope 55Mn Who discovered Manganese and when?īecause, there are only five electrons in the d-orbitals. Silvery white metallic State (at STP) Solid Position in Periodic table Manganese Element (Mn) Information Appearance So if you want to know anything about manganese element, then this guide is for you. In fact, the table mentioned below is the perfect information box (Which gives you every single detail about the Manganese element in Periodic table.) This is a SUPER easy guide on Manganese element.
