An ion is an atom or group of atoms that has an electrical charge from having either gained or lost electrons. An ion may have either a positive or a negative charge. An electron is a subatomic particle that carries a negative charge and is usually found in the orbitals of atoms and ions.

Ions are charged.
Atoms are neutral species containing protons and neutrons in the nucleus and electrons in the orbitals (or shells). Ions are formed when an atom gains or loses electrons. If an atom gains electrons, then negatively charged ions called anions are formed. If an atom loses electrons, then positively charged ions called cations are formed.
There are two types of charges of ions that are the negative and the positive charges. Ionic bonding is between 2 types of elements;the metals and non-metals. Metals loose electrons while non-metals gain electrons. when they form ions they obtain charges. The metals always gain a positive charge as they loose electrons while the non-metals always gain a negative charge as they gain electrons.
One has gained electrons and the other has lost electrons
Covalent bonds involve the sharing of electrons between atoms, and ionic bonds involve the gain and loss of electrons, which forms ions.
In an ionic bond electrons are transferred and the bond is due to electrostatic attrcation between oppositely charged ions. in a covalent bond the electrons are shared .
Ionic bonds are formed by electrostatic forces between ions whereas covalent bonds are formed by sharing of electrons.
Electrons
An ion is certain type of atom. Ions are atoms that have lost or gained electrons (often to have 8 valence electrons in the s and p orbitals).
molecular orbital.
In an ionic bond all of the electrons are localised to the ions, none are shared or free to move. In a metallic bond electrons are free and able to move about the lattice in the solid or the melt.
Ionic bonds are based on the electrostatic attraction of ions; covalent bonds are based on the sharing of electrons between two atoms.
electrons*
electrons are shared between all aluminum ions in the bar
In a covalent bond electrons are shared between atoms. In an ionic bond electrons are transferred from one atom to another, resulting in oppositely charged ions.
