An ion is an atom or a group of atoms in which the number of electrons is different from the number of protons. If the number of electrons is less than the number of protons the practical is a positive ion, also called a cation. Ex : sodium ion Na+ , chloride ion cl- , and oxide ion O2 -.
An ion is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons.
Ions are formed by the gain or loss of electrons to or from neutral atoms or molecules
One example of an ion is the sodium cation (Na+). The sodium cation is formed when a sodium atom loses one electron. This leaves the sodium atom with one more proton than electron, giving it a net positive charge.
