I think that the electrons cannot be gained or loosed or shared electrons in valence shell.
They are lost.
They may be lost, gained, or shared.
The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
In metallic bonding, the valence electrons freely 'jump' from atom to atom, forming kind of an electron sea.
The valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding. The electrons more loosely held by the nucleus - are the ones that are gained, lost or shared.
They are the electrons in the (outer) valence shell
Valence electrons
the valence electrons are shared.
Non-Bonding Electrons
In a covalent bond electrons are shared between two electrons.
