Why does oxygen accept a pair of electrons instead of donating one electron so as to become half filled (1s^2,2s^2,2p^3) ? Isn't it easier to give one that to take two?

Solution

Dear Student,

An atom donates and accepts electrons to attain a stable electronic configuration oxygen is a non metal and also highly electronegative. Non metals accept electrons pairs rather than donating it and so does electronegative atoms. Therefore, it is easier to gain electrons and attain full filled configuration rather than losing electrons.

Hydrogen is having one electron. To complete its duplet, it should gain one electron. Then it should become Hydride(H- )ion. But how can it loose one electron to form Hydeogen (H+) ion ? Why does it do so as it is gaining no stability ?

As known to us hydrogen has only one electron

So to make an ion it would give electron or take electron
