Description
Transition Elements
- d-block elements
- Electrons are filling d orbitals
- Highest energy sub shell is a d sub-shell
- Electrons are filling d orbitals
- A d-block element that forms an ion with an incomplete d sub shell.
Annotations:
- Scandium and Zinc are not classed as transition metals; as they have completely empty and completely full sub shells respectively.
- Electron Configurations
- The arrangement of the electrons in an atom.
- S:2, P:6, D:10, F:14
- Follow the same pattern except chromium and copper
- Chromium: 3d & 4s orbitals all contain one electron
- Copper: 3d orbital full, but only 1 electron in 4s
- Electron repulsions between outer electrons is minimised
- Chromium: 3d & 4s orbitals all contain one electron
- The arrangement of the electrons in an atom.
