Question

Explain the classification of elements into
different blocks? Explain the characteristics of each
block.​

Answer 1

Elements in the long form of periodic table have been divided into four blocks i.e. s ,p ,d and f. This division is based upon the name of the orbitals which receives the last electron. ... 2)s sub shell has only 1 orbital which can accommodate only 2 electrons, therefore, there are only two groups of s block elements.

Answer 2

Answer:

Elements in the long form of periodic table have been divided into four blocks i.e. s ,p ,d and f. This division is based upon the name of the orbitals which receives the last electron.

1)Elements in which the last electron enters the s orbital of their respective outermost shells are called s block elements.
