Noble Gas Electron Configurations

Elements with 8 valence electrons is known to have a

• duplet electronic structure

• octet electronic structure

• heptet electronic structure

Not all atoms have duplet or octet electronic configurations. Atoms can lost, gain or share electrons to achieve noble gas electronic configurations. An atom of 2,8,7 electronic configuration can achieve stability by

• gaining 1 electron to form positive ion

• gaining 1 electron to form negative ion

• losing 1 electron to form positive ion

• losing 1 electron to form negative ion
