What is the properties of manganese?
Manganese is a pinkinsh-gray, chemically active element. It is a hard metal and is very brittle. It is hard to melt, but easily oxidized. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids.
Is manganese a stable element?
Naturally occurring manganese consists of one stable isotope: 55Mn. In addition, 18 radioisotopes have been characterized, of which the most stable is 53Mn, with a half-life of 3.7 million years. The isotope 54Mn has a half-life of 312.3 days, and 52Mn has a half-life of 5.591 days.
What is the freezing point of manganese?
1,246 °C

Why is manganese a transition metal?
Manganese is a transition metal, according to Chemicool. Transition metals are ductile, malleable and conduct electricity and heat. Pure manganese is reactive, burns in oxygen, rusts in water and dissolves in dilute acids, according to Lenntech.
Is manganese compound or element?
Manganese is a chemical element with symbol Mn and atomic number 25. Classified as a transition metal, Manganese is a solid at room temperature.
Is manganese a solid liquid or gas?
What is the freezing point of manganese ( Mn )?
Freezing point of Manganese (Mn) is 1246 °C [ Convert 1246 °C to different units ]
What are the facts about the element manganese?
Manganese Basic Facts. Properties: Manganese has a melting point of 1244+/-3°C, boiling point of 1962°C, specific gravity of 7.21 to 7.44 (depending on allotropic form), and valence of 1, 2, 3, 4, 6, or 7.
Which is the most stable isotope of manganese?
Isotopes: There are known 25 isotopes of manganese ranging from Mn-44 to Mn-67 and Mn-69. The only stable isotope is Mn-55. The next most stable isotope is Mn-53 with a half-life of 3.74 x 10 6 years.
How is manganese used as an alloying agent?
Manganese Basic Facts. Uses: Manganese is an important alloying agent. It is added to improve the strength, toughness, stiffness, hardness, wear resistance, and hardenability of steels. Together with aluminum and antimony, especially in the presence of copper, it forms highly ferromagnetic alloys.
