Question

Which of the following general electronic configurations are CORRECTLY matched with their respective blocks in the modern periodic table?

Answer: A,B,C,D

💡 Solution & Explanation

The general outer electronic configurations classify elements into blocks. s-block has 1 or 2 valence electrons in the outermost s-orbital. p-block has $ns^2$ filled and fills $np$ from 1 to 6. d-block fills the penultimate d-subshell with outer s-electrons (sometimes 0, e.g., $Pd$). f-block fills the antepenultimate f-subshell while maintaining 0 or 1 electron in the penultimate d-subshell and a filled outermost s-subshell.
