Elements of group 8A of the periodic table are known as the noble gases. Determine which of the following properties are characteristic of all naturally occurring noble gases.
A) Have an outer electrons configuration of ns2np6
B) Form no stable chemical compounds
C) Have a substantial affinity for electrons (large negative Eea value)
D) Have a large ionization energy
The main group elements of the periodic table are those found in groups 1A through 8A. The members of a group exhibit similar properties owing to the similarity in their outer electron configurations. Although the properties are similar, they are not identical, and they vary from top to bottom of a column. As a result, each element has a unique set of properties that can be used to identify it.
