Which of the followingstatements related to the modern periodic table is incorrect?
(a) The p-block has 6 columns, because a maximum of 6electrons can occupy all the orbitals in a p-shell.
(b) The d-block has 8 columns, because a maximum of 8electrons can occupy all the orbitals in a d-subshell.
(c) Each block contains a number of columns equal to the number ofelectrons 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 theelectronic configuration.
