Boiling Point: 2,061Manganese
A member of the Periodic Table since 1774,
There is a large quantity of this element on the ocean floor.
Grayish-white, a metal, and a solid, too,
This element is the twenty-fifth known to me and you.
Known as a transition metal, it produces a magnetic field,
But its toxication level seizes to yield.
Exposure to dust, fumes, or a compound must not occur,
Or there will be a side effect that your body will endure.
Resembling iron, brittle, and hard,
This element many even be found out in the yard.
For it is plentiful in the earth's crust, and throughout the animal kingdom, this element is a must.
By now you may have guessed to which element this description pertains,
So I will give you the answer to the question that remains.
All of these qualities should give you a clue.
Manganese is this element known to me and you.

Solid The crystal structure of manganese.Classification: Metal
Group/Family:
Manganese belongs to group seven in the Periodic Table of Elements. The elements in group seven are classified as transition metals.Origin of Name: The name of this element comes from the Latin word "magnes" or "magnet." It also originates from the words "magnesia nigri," which mean "black magnesia."
The Discovery:
In 1774, Johann Gahn discovered Manganese in Sweden. The element was discovered when Gahn reduced the dioxide by heating charcoal, and the result was a sample of metal manganese.Color: Silvery metallic or grayish-white
Cost:
$100 for one gramDescription: Manganese is a grayish-white element that resembles iron. It is hard and brittle, which means that in physical characteristics, manganese can easily break apart.
The Uses of Manganese
Manganese is used to form many important alloys, or a mixture or solid solution of two or more metals which are the same. In steel, manganese improves a sudden increase in toughness and strength. The dioxide in manganese is used before dealing with oxygen and chlorine, and before drying black paint. It also eliminates contact between dry cells, and is used to remove the color from green glass that has been contaminated by iron. Manganese is important in the use of vitamin B. It is a powerful element, which combines with oxygen to be used in many experiments and medicines.
Sources
The most common manganese minerals that are distributed are oxides, silicates, and carbonates. The discovery of manganese nodules, or small masses of tissue on the floor of the ocean, contain about 24% manganese together with other elements. Manganese can be found in Russia, Brazil, Australia, the Republic of South Africa, Gabon, and India. Two of the most common manganese minerals are pyrolusite and rhodochrosite.
Handling
Manganese has a high toxicity level, and exposure to manganese dust, fumes, or compounds should not occur for even short periods of time.
Did You Know?
Manganese is available commercially, and is used in steel industries as ferromanganese. Manganese is present on the floors of oceans. The compounds in this element are essential, or needed for life, and for the actions of enzymes. This element can be found in steel, batteries, and ceramics. Manganese is also a wide resource throughout the animal kingdom, and a lack of this element may lead to infertility in mammals.
