Solution
The tendency of an element to form anion is the nonmetallic character of that element.
Explanation:
Nonmetallic character is defined by an element’s ability to gain electrons to achieve a stable electronic configuration, thereby forming negative ions, known as anions. Elements on the right side of the periodic table generally exhibit this behaviour due to their high electronegativity and high ionisation enthalpy.
