Question

Which 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-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 number of electrons that can occupy that subshell
(d) The block indicates value of azimuthal quantum number (I) for the last subshell that received electrons in building up the electronic configuration

Answer 1

The option (b) represents incorrect statement. It states that
"The d-block has 8 columns because a maximum of 8 electrons can occupy all the orbitals in a d-subshell."
The correct statement is
"(b) The d-block has 10 columns because a maximum of 10 electrons can occupy all the orbitals in a d-subshell"
