Electronic configurations and oxidation states
هتفهم الـ 3d بتتملي إزاي، مين بيطلع الأول في الـ ions، وإيه اللي يخلّي العنصر transition.
الدروس

- Ions (cations and anions)
- Oxidation state in compounds
- Oxidation and reduction by electrons
- Atomic radius trend
- Ionization potential (ionization energy)
- Electronic configuration of the first transition series
- Abnormal electronic configuration of chromium and copper
- Ions: 4s electrons are lost first
- Iron(II) is easily oxidized while manganese(II) is not
- Oxidation states from Sc to Zn
- Why several oxidation states
- Definition of the transition element
- Are coinage metals and zinc transition elements?
