S-, P-, D-, and F-Block Elements
Introduction
- Elements are classified into four blocks based on the location of their valence electrons: s-, p-, d-, and f-blocks.
- The block assignment determines the chemical properties and behavior of the elements.
S-Block Elements
- Group 1 (alkali metals) and Group 2 (alkaline earth metals)
- Valence electrons in s-orbitals
- Highly reactive, form 1+ (alkali metals) and 2+ (alkaline earth metals) ions.
P-Block Elements
- Groups 13-18
- Valence electrons in p-orbitals
- Wide range of properties, including metals, nonmetals, and metalloids
- Form diverse compounds with varying oxidation states.
D-Block Elements (Transition Metals)
- Groups 3-12
- Valence electrons in d-orbitals
- Transition metal ions form colorful complexes with various ligands
- Exhibit variable oxidation states and catalytic properties.
F-Block Elements (Inner Transition Metals)
- Lanthanides (Group 3) and actinides (Groups 4-5)
- Valence electrons in f-orbitals
