Find out how the electron configuration of sodium ... Examine how sodium and chlorine atoms combine to form the compound sodium chloride (ordinary table salt).

The atom that gains an electron becomes a negative ion. A positive and negative ion attract each other and form an ionic bond. Students will look at animations and make drawings of the ionic bonding ...

Atoms with incomplete valence shells generally form bonds with other atoms or elements to achieve a stable electron configuration ... For example, in sodium chloride (NaCl), sodium donates ...

The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the other atom ...
