Which of the following statements related to the modem periodic table is incorrect? (a) The p-block has six columns, because a maximum of 6 electrons can occupy all the orbitals in a p-subshell. (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 (l)for the last subshell that received electrons in building up the electronic configuration.
