Study Notes
Periodic Table Classification
- The d-block corresponds to the transition metals.
f-Block Characteristics
- The characteristic orbital for the f-block in the periodic table is the f-orbital.
Main Group Elements
- Main-group elements typically consist of the s- and p-block elements in the periodic table.
Borderline Cases
- Zinc, cadmium, and mercury are sometimes regarded as main-group elements due to their chemical properties, which are similar to those of the p-block elements.
- The group 3 elements (Sc, Y, La, and Ac) are occasionally considered main group elements, although they are formally part of the d-block, as their chemical properties resemble those of the main-group elements.
