4 Be, 6 C, 8 O, 5 B, 13A1 Which is the most electropositive element among these?

Question

Write down the electronic configuration of the following elements from the given atomic numbers. Answer the following question with explanation.

d.₄Be,  ₆C, ₈O, ₅B, ₁₃Al  Which is the most electropositive element among these?

Answer 1

₄Be,  ₆C, ₈O, ₅B, ₁₃Al

elements and thier electronic configuration :

₄Be=2,2

  ₆C=2,4

₈O=2,6

 ₅B=2,5

 ₁₃Al=2,8,3

The most electropositive element is ₁₃Al electropositivity increases down a group while it decreases moving across a period from left to the right
