PART_9 WHAT IS OCTET RULE?The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell.How do you calculate octet rule?The octet rule states that each atom should have 8 valence electrons to be satisfied. First, determine the number of electrons from lone pairs and bonds to the atom.What are exceptions in octet rule?General exceptions to the octet rule include molecules that have an odd number of electrons and molecules in which one or more atoms possess more or fewer than eight electrons.Which elements obey the octet rule?The octet rule is only applicable to the main group elements. The molecules of the halogens, oxygen, nitrogen, and carbon are known to obey the octet rule.Which elements break the octet rule?There aren't enough electrons in hydrogen, beryllium, or boron to make an octet.Well!! Thanks for all!
