is general valence shell electron configuration of halogens. So this configuration belongs to bromine.
( 
; This is electron configuration of 
-block elements. As it contains 
configuration, it belongs to copper.
; This is electron configuration of 
-block elements. As it contains 
configuration it belongs to chromium.
Noble gases has valence shell electron congiruation 
, so it belongs to krypton.
