Hint: When the charge on the ion is positive then the element is called electropositive and if the charge on the ion is negative then the element is electronegative. Mostly electropositive elements are placed on the left side of the periodic table and the electronegative elements are placed right to the periodic table.

For example: Sodium element has configuration $1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{1}}$. So it has one valence electron in its outermost shell, which it can lose and become stable. Therefore on losing one electron it acquires a positive charge ($N{{a}^{+}}$) and is an electropositive element.
The Fluorine element has configuration $1{{s}^{2}}2{{s}^{2}}2{{p}^{5}}$. So it needs only one more electron in its outermost shell. So it has a strong tendency to attract an electron. Therefore by gaining one electron it acquires a negative charge (${{F}^{-}}$) and is an electronegative element.
Note: The elements form positive ion or negative ion only to acquire the nearest noble gas configuration which is the most stable configuration. So, $N{{a}^{+}}$ has the configuration the same as neon, and ${{F}^{-}}$ also have the same configuration as neon.
