In the third major energy level, it has one valence electron. All non-metals gain two or more electrons and do not lose any proton. Ans: When ionic compounds dissolve in water, they break into individual ions; thereby leading to the process of dissociation. You must know that each atom is unique due to its particular number of protons, neutrons, and electrons. Likewise, sodium ions are very different than magnesium ions, fluoride ions, and all the other members of this isoelectronic series (N 3 , O 2 , F , Ne, Na + , Mg 2+ , Al 3+ ). The periodic table helps to predict whether an atom will form an anion or a cation, and also the charge of the resulting ion. In cation, the number of electrons is less compared to the number of protons forming a net positive charge. Calcium (Ca2+), potassium (K+), and hydrogen (H+) are examples of cations. An anion interacts with the solvent in the liquid state to generate solvated ions, which are significantly more stable. Ionic compounds are the ones that are bonded by the ionic bond between the atoms of an element. Cations, on the other hand, can exist in both liquid and solid states. A cation is formed when a metal ion loses a valence electron while an anion is formed when a non-metal gains a valence electron. There is a strong force of attraction between positive and negative ions, which makes ionic compounds solid and not easily breakable.
