compare the possession of electrons in ionic and covalent bonds.?

Answer 1

Covalent bonds are a sharing of electrons. The electron exist in orbital clouds between the two atoms. Ionic bonding is a complete exchange of electrons. For example, in table salt, sodium chloride, the chloride atoms exists as ions, or more specifically Cl -1 . The the chlorine completely steals an electron from the sodium and it is the ionic attraction between the negative ion and the positive iion that holds them together. in a covalent molecule, say ethanol (C2H6) neither carbon is an ion, they share electrons between them. There is probably some much more complex mechanics happening here, but for a question in the biology section, this will do
