Explain how the elements are classified into s, p, d and f block elements in the periodic table and give the advantages of this kind of classification?
Answers
Answer:
All the elements are classified into s, p, d and f on the basis of presence of last electron. For example if last electron of element falls in the s orbital then the element will be placed in s block. This kind of classification makes the study easier.
Answer: Depending on the valency shell electronic configuration elements are classified into s,p,d and f - block elements.
s-block elements : The elements with valence shell electronic configuration ${{ns}^{1}}$ and ${{ns}^{2}}$ are called s-block elements.
p - block elements : The elements with valence shell electronic configuration ${{ns}^{2}}$${{np}^{6}}$ are called p-block elements.
s and p-block elements together known as representative elements, d - block elements : The elements with valence electronic configuration from ${{ns}^{2}}$${{np}^{6}}$(n - l)${{d}^{1}}$ to ${{ns}^{2}}$${{np}^{6}}$ (n - l)${{d}^{10}}$ are called d-block elements. These are also called as transition elements.
f - block elements : The elements in which f - orbitals are being filled in their atoms are called f - block elements. These are also known as Inner Transition elements.
Advantage : This division of elements into blocks is useful to divide the elements into groups. Every group has the elements with some valence electronic configuration. They have similar chemical properties,
s - block elements - IA and IIA groups
p - block elements - IIIA to VIIIA or zero group
d- block elements - IB to VIII B groups
f - block elements - Lanthanoids and Actinoids
