How can an atom achieve octet?

David: By transfer of electrons atoms- can attain octet Dravid: By sharing of electrons atoms- can attain oclet

What is valency of an atom? Explain how an atom can achieve an octet in their outermost shell and also explain how an atom can be chemically stable.

Assertion : In the formation of water octet molecule, both hydrogen and oxygen atoms attain octet of electrons. Reason : Oxygen atom forms two ionic or electrovalent bonds with two hydrogen atoms.

The atom of an element ( not helium ) contains two electrons in its valence shell . How will the atom complete its octet ?
