Which group of elements could be placed in Mendeleev's table without disturbing the original order ? Give reason

${\huge{\underline{\orange{\bf\tt{Answer:} } }}}$

The elements of group 18, that is inert gases or noble gases can be placed in Mendeleev's table without disturbing the original order.

Inert gases include

• Helium
• Neon
• Argon
• Krypton
• Xenon
• Radon
• Oganesson

These elements can placed in the Mendeleev's table without any disturbance because inert gases have 8 valence electrons and have a special electronic configuration, so, they can be put in a separate group without disturbing the rest.

Also, while designing the table, he left the space for non-discovered elements.

Fun fact:Dmitri Mendeleev got the idea and design of periodic table in his dream.
