Question

On the basis of electronic configuration how will you
classify-
1 chemically similar elements
2 the first element of a period
3 a group of alkali metals
4 a group of halogens
5 a group of inert gases

Anuradha Puri · Accepted Answer

1) 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
