Ionic bonds
In sodium metal the atoms are held together by metallic bonds.
When an electron of sodium atom is transferred to chlorine atom it forms sodium chloride. This chemical bonding gives Na+ and Cl-. The electrons are of opposite charges so they are attracted to each other and the end result is the formation of NaCl.

ionic bonds :)
Sodium chloride does not have an overall charge, it only has charged ions (which are Na+ and Cl-) If a sodium atom meets a chlorine atom, the sodium loses its outer-shell electron to form the sodium ion Na+. Chlorine takes on sodium's electron to become the ion Cl-. It also has a new name: chloride. Both ions are more stable than the neutral atoms from which they were formed, and exist as NaCl, sodium chloride (common salt). The electrostatic attraction between the positive and negative ions holds the salt crystal together. (Note that in the final formula the charges are not shown, although each ion still has its charge.)
The transfer of electrons from the sodium to the chlorine, bicarbonate, ect.
Ionic Bond
Sodium chloride has ionic bonds.
Ionic bonding
When sodium atoms and chlorine atoms interact, the sodium atoms are converted to positively charged cations and the chlorine atoms are converted to negatively charged anions. The cations and anions to which the atoms have been converted are held together by mutual electrostatic charge attractions.
Chemical bonding
The attraction between the two are called ionic forces or ionic bonds.
In sodium metal the atoms are held together by metallic bonds.
It is the electromagnetic force as it is expressed in what is called an ionic chemical bond that holds individual molecules of table salt (NaCl) together.
Covalent Bonds holds two non-metals such as Silicon Oxide. Ionic Bonds holds a metal and a non-metal such as Sodium Chloride.
An Ionic Compound is a compound that is formed when electrons exchange atoms. For example, Chlorine Gas will react with Sodium to create Sodium Chloride (NaCl, more commonly know as table salt). Chlorine gains an electron from sodium. The chlorine atom (now an ion) is then negatively charge (an anion) and the sodium ion is positively charge (cation). Different charges attract, so that's what holds them together.
The salt molecules are "torn apart" by the water, and are reduced to sodium (Na+) and chlorine (Cl-) ions. It is the ions that go into solution and "float around" there. Note that elemental sodium and elemental chlorine are not what is in solution. The ions are. Salt, sodium chloride, is an ionic molecule; an ionic bond holds salt together.
