Why do the two electrons spend their time equally between both hydrogen atoms? In other words, why can’t one hydrogen just take the other’s electron?

Respuesta :

Because it is a covalent bond meaning that they share the electrons to achieve full valence.
  • There is a single bond present between Hydrogen and hydrogen.
  • Hydrogen has valency 1
  • So inorder to complete octet both electrons share 1 electrons.
  • So they has restriction only to acquire covalent bonded electron not others
