GCSE Chemistry Revision "Ionic Bonding 2: Ionic Bonding between Group 2 and Group 6"
Freesciencelessons・2 minutes read
Ionic bonding involves the transfer of electrons between metals and non-metals to form stable ions with complete outer energy levels, demonstrated through dot and cross diagrams in chemistry exams. In the case of magnesium reacting with oxygen, magnesium loses two electrons to become a two positive ion, while oxygen gains these electrons to become a two negative ion.
Insights
- Ionic bonding occurs between group two metals and group six non-metals through electron transfer, creating ions with full outer energy levels akin to noble gases.
- The use of dot and cross diagrams effectively demonstrates the electron transfer in ionic bonding, emphasizing the attainment of stable outer energy levels by metals losing electrons and non-metals gaining them.

Ionic Bonding: Metal to Non-Metal Electron Transfer
- Ionic bonding involves the transfer of electrons between group two metals and group six non-metals, resulting in the formation of ions with full outer energy levels resembling noble gases.
- In the example of magnesium reacting with oxygen, magnesium loses two electrons from its outer energy level, becoming a two positive ion, while oxygen gains these electrons, becoming a two negative ion, achieving stability.
- Dot and cross diagrams can illustrate this ionic bonding process, showcasing the transfer of electrons from the metal to the non-metal, leading to the formation of ions with complete outer energy levels, a key concept in chemistry exams.
