Page 1: Fundamental Properties and Basic Reactions of Manganese
The first page introduces manganese's basic properties and chemical behavior. Manganese is characterized as a noble metal with typical metallic properties, positioned above hydrogen in the electrochemical series.
Definition: Manganese is a d-block element with electronic configuration 4s²3d⁵, featuring 7 valence electrons.
Highlight: The mangan stopnie utlenienia include +2, +3, +4, +5, +6, and +7, each producing distinctive colored compounds.
Example: A key reaction showing manganese's basic behavior: Mn + HCl → MnCl₂ + H₂
Vocabulary: Aluminothermic process - A method to obtain manganese: 3MnO₂ + 4Al → 2Al₂O₃ + 3Mn
The page also details manganese oxides' chemical characteristics:
- MnO (basic)
- Mn₂O₃ (basic)
- MnO₂ (amphoteric)
- Mn₂O₇ (acidic)
