The Modern Periodic Table is based on the atomic number. Explain this with a table.

Which of the following statements is incorrect?

The element with the lowest atomic number that has a ground state electronic configuration of $(n - 1)d^6 ns^2$ is located in the

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 $(l)$ for the last subshell that received electrons in building up the electronic configuration.
