No they are composed of elements that are present in the periodic table but as compounds they are not listed.
Manganese. Transition metal ions exhibit electron transitions between their electron orbitals which absorb light of certain wavelengths, making the compound coloured.
"Manganese acetate" probably means more exactly manganese (III) acetate and "manganous acetate" almost certainly means manganese (II) acetate. Under this assumption, the difference between the two compounds in the question is that manganese acetate tetrahydrate has the formula Mn(C2H3O2)3. 4 H2O has the formula Mn(C2H3O2)2. 4 H2O.
Well, taking Manganese for example. Manganese is a chemical element, designated by the symbol Mn. In chemical Industry, manganese can be applied for making various manganese compounds such as manganese sulfate, manganese chloride, and potassium permanganate.Manganese mining and processing methods include mechanical separation, which includes ore crushing, washing, screening, gravity separation, high-intensity magnetic separation, and flotation separation, hydrometallurgy enrichment and chemical mineral processing method etc.

Manganese(II) is a chemical compound where manganese has a +2 oxidation state. It is an important nutrient for various biological processes and is commonly found in foods and supplements. Sulfur(III) is not a commonly encountered oxidation state of sulfur in chemical compounds. The most common oxidation states of sulfur are -2, +4, and +6. It is important in many biological processes and is present in various compounds, such as sulfur dioxide (SO2) and sulfur trioxide (SO3).
The chemical symbol Mn stands for manganese.
