Usually electroposititve elements refers to an element whose atoms tend to lose electrons; e.g., sodium, potassium, calcium. An element that is electropositive in one compound may be electronegative in another, and vice versa.
An electronegative element has a tendency to gain electrons. It forms negative ions (anions) due to electron gain.So those atoms which have the tendency to gain electron are called as electronegative atoms.
In the above example it is clearly visible that sodium atom is electropositive and chlorine is electronegative
