Why do you think the noble gases are placed in a separate group?
(N/A) Noble gases are chemically inert elements because they have a stable electronic configuration with a complete octet (or duplet in the case of Helium).
Their chemical properties are significantly different from all other elements in the periodic table.
Due to their unique stability and lack of reactivity,they are placed in a separate group,known as Group $18$.
