MCQ
Which element has the greatest tendency to loose electrons
  • A
    $F$
  • B
    $S$
  • $Fe$
  • D
    $Be$

Answer

Correct option: C.
$Fe$
c
(c) Both $Fe$ and $Be$ are metal but $Be$ has stable configuration so it is difficult to release ${e^ - }$ from it.

So it has less metallic character than $Fe$.
