The atoms that have fewer than eight electrons around them are to be stated. Also, the atoms having more than eight electrons around them are to be named. The reason behind the odd-electron species being very reactive is to be explained. Concept introduction: The chemical rule according to which the atoms tend to combine in a way that they have eight electrons in their outermost shell is known as the octet rule. But there are some molecules having fewer than eight, larger than eight or an odd number of electrons that do not follow this rule. To determine: The atoms that having fewer than eight electrons, the atoms having more than eight electrons and the reason behind the odd-electron species being very reactive.

Select 2 fluorine atoms. How many valence electrons are in each fluorine atom?
Is a fluorine atom a metal or a non-metal?
Did the combination of these atoms create a covalent or ionic bond?
How are the valence electrons organized to form a bond between these atoms?
How is this different from the ionic bonds formed in the previous part of the activity?
