Hint:The radicals which are not positively charged and are negatively charged are known as basic radicals. These basic radicals are formed when the hydroxide ions OH . The radicals are of two types – acidic radicals and basic radicals.

Complete answer:
A radical is an atom or group of atoms of an equivalent or of various elements that behave as one unit with a positive or charge. A radical could also be a basic radical (having a positive charge, that is, cation). A radical could also be an acidic radical (having a negative charge, that is, anion). They can form chemical formulae by using combining power because they have their own combining power.
The radicals are of two types –
Acidic radicals: The radicals which are negatively charged are known as acidic radicals. These types of radicals are formed by the removal of hydrogen H+. This makes the compound acidic radical. For example - H2SO4 loses one H+ to form HSO4 ion.
Basic radicals: These types of radicals can be defined as the positively charged radicals. When the hydroxide ion OH is removed from the compound then the resulting ion becomes the basic radical. For example - KOH loses OH ion and becomes K+ ion.
Some of the other examples of basic radicals are - Na+,Fe2+,Ag+,Al3+,Cr3+,Au3+,Co2+,Ni2+,Hg2+,Sn2+ etc.

All the radicals written above are positively charged therefore, these all are basic radicals.

Note: A radical is an atom, molecule, or ion that has an unpaired valence electron. With some exceptions, these odd electrons create radicals highly chemically reactive. several radicals spontaneously dimerize.
