Periodic table block
From Wikipedia, the free encyclopedia.

In the periodic table, the areas known as blocks are named after atomic orbitals.

Names of periodic table blocks:

• s-block
• p-block
• d-block
• f-block
• g-block

Some blocks contain several periodic table groups (eg the s-block contains groups 1 and 2); others correspond to chemical series.
