Had three electrons been possible to be placed in an orbital, the block of potassium in periodic table would be:

If each orbital can take maximum of three electrons, the number of elements in the third period of the periodic table will be:

If each orbital can take maximum of three electrons, the number of elements in the third period of the periodic table will be:

The general electronic configuration of an element belonging to the p-block of the periodic table will be represented by

Why has the zero group been placed at the extreme of the periodic table?

Predict the maximum number of valence electrons possible for atoms in the first period of the periodic table.
