Xenon will be the central atom because fluorine cannot be a central atom: Step 3: Distribute the remaining electrons. A double bond forms when two pairs of electrons are shared between a pair of atoms, as between the carbon and oxygen atoms in CH2O (formaldehyde) and between the two carbon atoms in C2H4 (ethylene): A triple bond forms when three electron pairs are shared by a pair of atoms, as in carbon monoxide (CO) and the cyanide ion (CN): For very simple molecules and molecular ions, we can write the Lewis structures by merely pairing up the unpaired electrons on the constituent atoms. As per rule, the total number of valence electrons an atom can accommodate in its outermost shell is eight. As s shell can accommodate up to two electrons, there is a scarcity of only one electron, a hydrogen atom needs only one valence electron to complete its shell.
