Which one of the following statements related to the modern periodic table is incorrect?

A

The p-block has 6 columns, because a maximum of 6 electrons can occupy all the orbitals in a p-subshell.

B

The d-block has 8 colums, because a maximum of 6 electrons can occupt all the orbitals in a p-subshell.

C

Each block contains a number of columns equal to the number of electrons that can occupy that subshell.

D

The block indicates value of Azimuthal quantum number `(l)` for the last subshell that received electrons in building up the electronic configuration.

Text Solution

Verified by Experts

The correct Answer is:
B

The `d`-block has 10 columns, because a maximum of 10 electron can occupy all the orbitals (5) in a `d`-subshell.
