Question

Identify the group number corresponding to each of the following families of elements: noble gases. a) Group 0 b) Group 8 c) Group 18 d) Group VIII

Answer 1

Final answer:

Noble gases pertain to Group 18 in the modern periodic table's IUPAC numbering system. In the older CAS system, they were referred to as Group VIII. Group 0 and Group 8 are not terms used to describe noble gases.

Step-by-step explanation:

The family of elements known as the noble gases corresponds to Group 18 on the periodic table in the IUPAC numbering system. These elements include helium, neon, argon, krypton, xenon, and radon. In the older CAS system, this group was often referred to as Group VIII. Options a) Group 0 and b) Group 8 are not used for referring to noble gases in modern terminology. The noble gases are characterized by their full electron shells and low reactivity.
