Students will look at animations and make drawings of the ionic bonding of sodium chloride (NaCl). ... Sodium loses an electron, leaving it with 11 protons, but only 10 electrons. Since it has 1 more ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...

Sodium and chlorine, two highly reactive elements, combine to form the stable compound sodium chloride (ordinary table salt). Questions for Discussion Describe the electron configuration of sodium.

So, sodium atom will donate one electron to chlorine atom and forms a sodium ion i.e. Na+. On the other side chlorine atomic number is 17 , its electronic configuration is 2,8,7 .
