Explain the relationship between the elements with outermost electrons assigned to s, p, d and f blocks and the organisation of the Periodic Table
In the periodic table:
- Similar outer shell electron configurations reoccur at regular intervals
- Electrons in similar configurations display similar chemical properties
- Elements with similar outer shell electron configurations occur in the same vertical group
- g Group 1 has s1 as outermost shell
- g Group 13 has s2p1 outer shell configurations
- As a result the periodic table is divided into four distinct blocks
- To determine filling order
- Going from top left then across successive rows
