Element X needs two electrons to complete its valence octet. Two X atoms share two electron pairs equally, establishing a double covalent bond to create a stable diatomic molecule with the structure X double bond X.
An element X has six electrons in its outer shell and forms a diatomic molecule. (i) Why would that be so? (ii) What kind of bond would it form? (iii) Draw the structure of the molecule it would form. (iv) A certain other element Y has two electrons in its second shell. Draw the structure of the molecule that X would form with Y.

Element X contains six valence electrons, meaning it requires two additional electrons to attain a stable octet configuration. Two X atoms achieve stability by sharing two pairs of electrons, resulting in a double covalent bond. When X reacts with element Y having two valence electrons, they share or transfer two electrons, yielding the stable compound Y double bond X or YX.
