Question

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

• A. The $p-$ block has $6$ columns, because a maximum of $6$ electrons can occupy all the orbitals in $p-$ shell.
• B. The $d-$ block has $8$ columns, because a maximum of $8$ electrons can occupy all the orbitals in a $d-$ subshell.
• C. Each block contains a number of columns equal to the maximum number of electrons that can occupy that subshell.
• D. The block indicates value of azimuthal quantum number for the last subshell that received electrons in building up the electronic configuration.

Answer 1

Answer: (B)

The $d-$ block has $10$ columns, because a maximum of $10$ electrons can occupy all the orbitals in $d-$ subshell.
