3. s- and p- block

4. f-block​​​​​

Q.

Which of the following statements related to the modern periodic table is incorrect?

1. The p-block has 6 columns, because a maximum of 6 electrons can occupy all the orbital in a p-shell.

2. The d-block has 8 columns, because a maximum of 8 electrons can occupy all the orbital in a d-sub shell.

3. Each block contains a number of columns equal to the number of electrons that can occupy that sub shell.

4. The block indicates value of Azimuthal quantum number (l) for the last sub shell that received electrons in building up the electronic configuration.
