A block of the periodic table of elements is a set of adjacent groups. The term appears to have been first used by Charles Janet. The respective highest-energy electrons in each element in a block belong to the same atomic orbital type.

The symbols s p d f in the periodic table are the electron orbitals in atoms of the elements. The blocks in the periodic table are labeled s block , p block , d block and f block.
s orbit can have 2 electrons in it. The group 1 and 2 are part of s block.
The groups in p block have in p orbitals from 1 to 6 electrons varying across the horizontal period. The number of s electrons remain the same.
The d block contains elements with electrons in the outermost orbit varying from 1 to 10 electrons in the d orbitals.
The f block contains elements with electrons varying from 1 to 14 in the f orbitals, across the horizontal period.
