Question
Which group on the Periodic Table is inert?
- Group 1
- Group 2
- Group 17
- Group 18
Hint:
Group 18 is the noble gas family.
The correct answer is: Group 18
- In the periodic table there are 118 elements arranged in 18 groups and 7 periods.
- Group 1 and 2 are called alkali metals and alkaline earth metals respectively and are quite reactive.
- Group 17 is called the halogen family is the most reactive group.
- Group 18 is the noble gas family and are inert.
Helium, Argon, Neon are inert. These days Xenon shows little reactivity with oxygen and has few compounds.
