Ionization and Shorthand Electron Configuration
This page introduces the concept of ion formation and shorthand notation for electron configurations. It emphasizes the importance of understanding how atoms transform into ions through electron transfer to achieve noble gas configurations.
Key points covered:
- Atoms become ions by gaining or losing electrons
- The goal of ion formation is to achieve a noble gas configuration fullyoccupiedoutershell
- Metals, including all transition elements, always lose outer electrons
- Elements in groups 1-3 lose electrons, while those in groups 5-7 typically gain electrons
- Group 4 elements are unique as they can both lose and gain electrons
Definition: Noble gas configuration refers to the electron arrangement of noble gases, characterized by a full outer shell of eight electrons exceptforhelium,whichhastwo.
The page provides a comprehensive table with examples of various elements, their atomic numbers, electron configurations, and the resulting ions after electron loss or gain. This table includes elements from main groups and transition metals, demonstrating the diverse behavior of elements across the periodic table.
Example: Lithium Li, with the electron configuration He 2s¹, loses one electron to form Li⁺ with the configuration He.
Highlight: The shorthand notation for electron configuration is extensively used, showing the noble gas core followed by the valence electron arrangement.
