Question

on the basis of electronic configuration of how will you identify

first part chemically similar elements

second part the first element of a period

please explain in proper way ​

Answer 1

Explanation:

The elements with same valence shell electronic configuration will be chemically similar because chemical properties of an element are determined mainly by valence shell configuration.

2) Each period of the periodic table begins with the filling of a new shell.Therefore, the first element of each period will have only one outermost electron.

3) Alkali metals have outer shell configuration of ns1

4) Halogens have outer shell configuration of ns2np5

5) Inert gases gave complete outermost shells.These have outer shell configuration of ns2np6
