WebAn ion (/ ˈ aɪ. ɒ n,-ən /) 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 … Ions may be larger or smaller than the neutral atom, depending on the ion's electric charge. When an atom loses an electron to form a cation, the other electrons are more attracted to the nucleus, and the radius of the ion gets smaller. Similarly, when an electron is added to an atom, forming an anion, the added electron increases the size of the electron cloud by interelectronic repul…
