Chemistry Concepts - 7 Ionic Bonds An atom which has 1 or maybe 2 electrons in its outermost energy level (shell) may donate (give up) these electrons, which results in an outer energy layer with full orbitals. This action results in an atom with more protons than electrons, which results in a charged atom, an ion. Example: Na 11p 11e ---> Na 11p 10e = Na (+1) ion A second atom may have 7 electrons in its outer shell, and may take on a

Unformatted text preview: donated electron to complete its orbitals. This too, produces a charged atom, or ion, but now one which is negatively charged. Example: Cl 17p 17e---> Cl 17p 18e = Cl (-1) ion The bond which forms occurs between the charges of the respective ions, forming a complex of positive and negative ions. This bond is called the ionic bond. Ions can be formed from atoms: or from molecules: Na + CO 3 = Cl-NH 4 +...
