Answer:
Sodium (Na) is the element with electronic configuration 2,8,1
Explanation:
As the complete electronic configurtion of any atom is like 2,8,8 ...
losing 1 electron is easier than gaining 7 electrons hence sodium become stable by losing 1electron by completing its octet as 2,8

a)The atomic number of element with electronic configuration 2,8,7=17.
(b)It has 7 valence electrons, therefore it would be chemically similar to F(9)=2,7.
