WebIf the number of electrons present in the outermost shell is 7, then its valency is again 1 (8 - 7 = 1) as it can accept 1 electron from the combining atom. In a given period, the number of electrons in the valence (outermost) shell increases from left to right. WebThe right O atom has two lone pairs of electrons and a double bond with the N atom. The N atom has a single lone pair of electrons in addition to the double and single bonds with oxygen atoms. The third image shows diazomethane, CH2N2, and the proposed Lewis structure has a carbon singly bonded to two H atoms, then doubly bonded to a nitrogen.
