When an atom gains or donates electrons to form an ion is called ionization. Hydrochloric acid with water and carbon dioxide with water are the ionization reaction.
<h3>What are Ionization reactions?</h3>
In ionization reactions, the chemical species undergo changes to gain or lose electrons to acquire charge.
The reaction between hydrochloric acid and water to yield hydronium ion and chloride ion, and the reaction between carbon dioxide and water to yield hydronium ion and bicarbonate ion is the example of ionization as electrons are donated and gained by the species.
Therefore, the ionization reaction results in the gain or loss of electrons.

The ground state ion that has unpaired electrons is <u>Sc²⁺ ion</u>; option C is correct.
<h3>
What is ground state ion?</h3>
The ground state ion is the state in which all its electrons are in the lowest energy orbitals possible. You can get positive ions by removing electrons until you reach a noble gas configuration.
Ground state ion configurations are the foundation for understanding molecular bonding, properties, and structures. From the electrons in an atom to the differing orbitals and hybridization, the ground state ion configuration throws light on many different atomic properties.
For example, the electronic configuration of Sc²⁺ is 1s²2s²2p⁶3s²3p⁶ 3d¹ 4s.
In conclusion, understanding electronic configuration leads to an understanding of the periodic table.

I believe it’s 39.0 if I’m not mistaken.
N2 has the optimal bond order of 3. To form N2+, one bonding electron is removed, giving a bond order of 2.5. Similarly, to form N2-, one antibonding electron is added, also giving a bond order of 2.5.
