Edexcel IAL Chemistry AS 2.16 Periodic blocks and subshells
Edexcel IAL Chemistry AS 2.16 Periodic blocks and subshells
Use the final occupied subshell to name the block, account for ionic electron loss or gain and state the maximum electrons in the requested subshell or shell.
How this is tested
- Identify s-, p- or d-block elements from atomic number or ionic electron count.
- Compare shell number and outer-electron count for elements in the same group.
- State maximum electron capacities of s, p and d subshells or named shells.
