Nitrogen and hydrogen atoms that make up ammonia (NH3) are held together by polar covalent bonds, where electrons are shared unequally. Nitrogen is significantly more electronegative than hydrogen, so shared electrons spend more of their time orbiting the nitrogen atom.
There are two ways to represent the chemical formula of a substance: in condensed form or in structural form. Ethane is an alkane which consist of two carbon atoms. Since the general formula for ethane is CₓH₂ₓ₊₂, the condensed formula is C₂H₆. The structural formula or the line-bond structure is shown in the attached picture.
