Manganese nodules are polymetallic concretions found on the ocean floor and are formed through a slow process of precipitation and accumulation of manganese and other metals. They are a type of sediment known as hydrogenous sediment, as they form directly from seawater and not from the breakdown of rocks or organic materials.
Manganese can form colored compounds such as manganese dioxide (black), manganese chloride (pale pink), and manganese sulfate (pale pink to light pink). These colors are due to the electronic structure of manganese ions in these compounds.
Metallic manganese reacts with oxygen to form manganese oxide (MnO), which can further react with oxygen to form higher oxidation states of manganese such as manganese dioxide (MnO2) or manganese trioxide (Mn2O3) depending on the conditions. These oxides play important roles in various industrial processes and are used in the production of batteries, ceramics, and fertilizers.
The oxidation state for manganese in Mn is 0, since it is in its elemental form.
Manganese itself does not rust, as rust is a form of iron oxide that occurs when iron reacts with oxygen in the presence of water. However, manganese can undergo oxidation and form its own compounds when exposed to certain conditions, but this is not the same as rusting.
They are formed in oceans as a result of pelagic sedimentation or precipitation

The chemical formula for manganese is Mn and for chlorine is Cl. When these two elements combine, they can form various compounds such as manganese(II) chloride (MnCl2) or manganese(IV) chloride (MnCl4), depending on the oxidation state of manganese.
It is a mistake. The isthmus of the thyroid gland is a thin bridge across the trachea, linking the right and left lobes. It occasionally also gives rise to the pyramidal lobe, a normal variant of thyroid anatomy. The adjectival form of isthmus is isthmic, so a nodule in the thyroid isthmus is an isthmic nodule, not an isthmal nodule.
When manganese touches water, a chemical reaction occurs where manganese may oxidize to form manganese oxide. The reaction can produce hydrogen gas and soluble manganese compounds in water.

Manganese is a metal. It is not soluble in water.
