Question

Definition of anion is:
A. negatively charged ion
B. positively charged ion
C. neutral ion
D. None of the above

Answer 1

Hint: During the electrolysis process, this ion moves towards the anode, and other ions move toward the cathode. They are usually larger in size as compared to the other ion as they carry extra electrons surrounding them.

Complete step by step answer:
Ions are species that carry a net electrical charge, as the charge present in the electron which is the negative species are equal and opposite to the proton which is the positive species. The net charge of the ion is not considered as zero as the total number of electrons is not equal to the total number of protons.
There are two types of ions present, one is a cation and one is an anion.
A cation is the positive charge species formed when the metal loses its one or more electrons.
Example: Calcium ($C{a}^{2+}$), Potassium ($K^{+}$).
Antion is the negative charge species formed when the non-metals accept one or more electrons.
Example: Chlorine ($C{l}^{-}$), hydroxide ($O{H}^{-}$).
Thus, the anion is the negatively charged ion.
Therefore, the correct option is A.

Additional information: The cation and anion are oppositely charged species which attract each other. The cations carry more proton than an electron as compared to an anion and the anion carries more electrons than proton as compared to cation.

Note:
The atom or molecule loses or gains electrons to form cation or anion but they do not lose their protons. Alkali metals elements and alkaline earth metal elements always generate cations and elements of the halogen group always form anions.
