In ionic bonds, electrons are ​ (a)   rather than being shared. When writing ​ a Lewis dot structure for an ionic compound, the elements' symbols are shown in a ​ (b)   with their charge and the electrons that make the ion stable. In a covalent bond, the valence electrons are ​ (c)   . When writing a Lewis dot structure for a covalent compound, the elements' symbols are written down, and the ​ (d)   electrons surround each symbol. At least one ​ (e)   of electrons are shared between the two elements.
