Atoms or molecule after gaining of electron possesses negative charge and is known as anion.

For the given sets:

[tex]Li, Na, K[/tex]

The given elements are alkali metals and have tendency to lose electrons easily and form cations.

[tex]N, O, I[/tex]

The given elements are non-metals and are electronegative. So, they gain electrons easily and form anion.

[tex]C, S, Pb[/tex]

Carbon has tendency to form bond by sharing of electrons, Sulfur has tendency to gain electrons and form anion whereas Lead has tendency to lose electron.

[tex]K, Fe, Br[/tex]

Potassium and Iron has tendency to lose electron and form cation whereas Bromine has tendency to gain electron to form anion.

Hence, from the given sets, all elements of set: [tex]N, O, I[/tex] have tendency to form anions in binary ionic compounds.

In the given set of elements, set II consisted of N, O, and I all forms the anions.

In a binary ionic compound, the atoms have been dissociated to form the anions and cations. The cations are the positively charged species, and anions are the negatively charged species.

The negatively charged species have been formed when an atom gains an electron. The more electronegative element tends to gain the electron more easily and has been able to form the anions.

For the given set of elements:

Li, Na, and K:

The elements have been the part of the alkali metals, and tend to easily lose an electron. The capability of the elements to form a cation.

N, O, and I:

The elements are non-metals and gain an electron easily, thereby they will be easily able to form the anions.

C, S, and Pb:

The elements carbon have been able to form the bonds with sharing of electrons. Sulfur has been the electronegative element and has been able to gain an electron forming an anion, while Lead has been the electropositive electron, and loses electrons thus forming a cation.

K, Fe, and Br:

Potassium has been the metal and loses electrons forming a cation. Fe and Br have been the non-metals, and gain electrons forming an anion.

Thus, in the given set of elements, set II consisted of N, O, and I all forms the anions.
