Answer» e the charged particle. You can say that ions are the charged ATOMS. They have EITHER positive, (+) or negative ( - ) charge on them. We know that the atom as a whole are neutral, that is, they have number of protons = number of electrons. If the ELECTRON is removed from the atom, then the number of electrons become less than the number of protons. Hence, the neutral atom becomes charged as the proton becomes GREATER in number than electron. Hence, it acquires a positive charge. These positive ions are called as cations. Example :- Na+ Now if electron is provided or acquired by the atom, than it becomes negatively charged as the number of electrons become greater than the number of protons. Since negative charge is greater in the atom, it becomes a negatively charged ION. These negatively charged ions are called as anionExample :- Cl- |
