GENERAL KNOWLEDGE

Detailed explanation-1: -An ion is an atom or group of atoms that has an electric charge. Ions with a positive charge are called cations. Ions with a negative charge are called anions. Many normal substances exist in the body as ions.

Detailed explanation-2: -An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

Detailed explanation-3: -An ion is defined as an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge. In other words, there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a chemical species.

Detailed explanation-4: -Ion :-It is an electrically charged atom or molecule formed by loss or gain of electrons. Ion formed by loss of electron is called cation.

Detailed explanation-5: -To find the ionic charge of an element you’ll need to consult your Periodic Table. On the Periodic Table metals (found on the left of the table) will be positive. Non-metals (found on the right) will be negative.
