metals tend to to lose electrons forming cations which are located on the left side of the periodic table. Non metals tend to gain electrons to fill their outer shell forming anions. These nonmetals are found toward the right side of periodic table.
Generally, p-block nonmetals form anions by gaining valence electrons until a noble gas electron configuration is reached. Nonmetals don't form cations because their ionization energies are too high to do so and instead form covalent bonds. Main group metals form cations by losing s and p valence electrons.
I agree with what is stated above. A good example of this is Na+ on the first column of the periodic table and Cl- in the 17th column on the periodic table. Na loses one electron by donating it to Cl. The Na+ is a cation and Cl- is an anion.
