Question

The eighth group of Mendeleev's periodic table is divided into how many subgroups?

• A. $2$
• B. $4$
• C. $0$
• D. $1$

Answer 1

Answer: (C)

In Mendeleev's, periodic table groups were divided into two subgroups.

1. Groups from $ItoVII$ are meant for normal elements, and group $VIII$ is for transition elements.
2. Groups $ItoVII$ have been divided into two subgroups while group $VIII$ is meant for three elements.

So the eighth group in Mendeleev's periodic table was not divided into any group.

Option $B$ is correct.
