The periodic table is divided into blocks based on electron configurations, including s and p orbitals, d orbitals, and f orbitals. These blocks help illustrate relationships between elements' electron configurations and their positions in the table, aiding in understanding periodic trends and chemical behavior.
The periodic table is divided into four blocks based on the orbital in which the last electron is placed: s and p orbitals (main group elements), d orbitals (transition elements), and f orbitals (inner transition elements).
The s-block contains the first two rows on the left side, the p-block consists of the right-most six columns, the d-block is the middle 10 columns, and the f-block is a separated section on the periodic table.
These blocks illustrate the relationship between an element's electron configurations and their placement, providing a framework for understanding periodic trends and chemical behavior.
