its based on its electronic configration ..if it has 2 or 3 valance electrons it may attract electrones
This number is different for each anion.
The elements in group-15 , 16 and 17 have 5,6 ad 7 valence electrons respectively , so they gain electrons to form anions.
Cations are formed by the loss of electrons, anions are formed by the gain of electrons. The force of attraction between cations and anions results in ionic bond.
Positive ions are called cations, and negative ions are called anions. Cations have a net positive charge because they have lost electrons, while anions have a net negative charge because they have gained electrons.
Valence electrons

If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.

Variable; a correct answer is possible only for a specified nonmetal.
Ionic bonds do not have valence electrons; rather, they form between atoms by electron transfer where one atom gives up electrons (cations) and the other gains electrons (anions). The resulting ions are held together by electrostatic forces, not by sharing electrons as in covalent bonds.
Anions in binary compounds are negatively charged ions that have gained electrons to achieve a stable electron configuration. In all types of binary compounds, anions are typically nonmetals that form anions by gaining electrons to fill their valence shell. These anions are named with an -ide suffix when combined with a cation.
Electrons in the outermost shell are valence electrons!
Valence electrons
Anions have supplementary electrons.
the electrons in the outermost shell of an atom are considered to be the valence electrons.
