Question

The atomic number of 5 elements a b c d and e are 6,8,3,7 and 9 respectively which is the element having the highest electropositivity among the elements and why

Answer 1

Electronic configuration of
Element a - (2,4)
Element b - (2,6)
Element c - (2,1)
Element d - (2,5)
Element e - (2,7)

Element c is the most electro positive as it is only only element which loses electrons to gain noble gas configuration.
Remaining elements gain electrons and becomes electronegative.

Answer 2

c is electropositive as it is lithium having electronic configuration (2,1)and it can easily loose one electron
