Ionic Bonding

Which group does noble gases belong to?

• Group I

• Group II

• Group VII

• Group 0

What does inert means?

• slow reaction

• unreactive and stable

• monatomic

• do not combine with other elements

Which of the following is electronic configuration belongs to an atom of noble gases?

• 2,8,1

• 2,8,8,2

• 2,8,8

• 2

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

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 2,8,2 electronic configuration can achieve stability by

• gaining 2 electron to form 2+ charge ion

• gaining 2 electron to form 2- charge ion

• losing 2 electron to form 2+ charge ion

• losing 2 electron to form 2- charge ion
