Because by definition, ionic bond is the force of attraction between positively charged cations and negatively charged anions. To form ions, atoms should be gained (resulting in anions) and lost (resulting in cations).
Ionic compounds are compounds with an electrical charge. That means that both cations (loss of electron) and anions (gain of electron) are ionic. In a salt where a cation and anion is combined the net sum of electrons is the same.
Covalent bonds involve the sharing of electrons between atoms, and ionic bonds involve the gain and loss of electrons, which forms ions.
An atom with incomplete octet tends to attain the noble gas configuration by the gain or loss of electrons. If an atom contains 2 electrons in its outer orbit, it would be more energy efficient for it to lose the two electrons and complete the octet, as opposed to gaining 6 electrons for the same.
Remember M.A.L.E and M.I.PMetalAtomsLoseElectronsMetalIonsPositiveHowever, non-metals gain electrons when forming ionic bonds, in order to gain a stable electron configuration. Because they gain electrons, they form negatively charged ions.
Electrons are either transferred between atoms to form ionic bonds or shared between atoms to form covalent bonds. Either way, bonds are formed through electrons.
Ionic bond
Cations are formed by the loss of electrons, anions are formed by the gain of electrons. The force of attraction between cations and anions results in ionic bond.
Ionic bonds involve an element gaining an electron and an element losing an electron.Ionic bonds differ from covalent bonds in that covalent bonds cause elements to "share" electrons, while in ionic bonds there is a distinct transfer of electrons.Ionic Bond.
ionic bonding
The ionic bond is formed by electrostatic attraction between two atoms.In the polar covalent bond the electrons sharing is unequally distributed between the two atoms, but the bond remain covalent.
Ionic and covalent bonding involve electrons. Ionic bonding involves the loss and gain of electrons, form ions. Covalent bonding involves the sharing of electrons.

ionic bonding- when a negatively charged atom is attract to a positively charged atom due to the loss or gain of a negatively charged electon.
An atom with incomplete octet tends to attain the noble gas configuration by the gain or loss of electrons. If an atom contains 2 electrons in its outer orbit, it would be more energy efficient for it to lose the two electrons and complete the octet, as opposed to gaining 6 electrons for the same.
I'm not sure why there would be a biography on an ionic bond but, ionic bonds are when atoms bond by transferring electrons.
Ionic bonds are formed when a Cation (loss of some # of e- makes it positive) and and Anion (gain of e- makes it negative) transfer electrons to/from each other in order to form a more stable compound. They will gain/lose e- in order to have full valence shells. Metallic bonding is different because there is an "Electron Sea" where electrons can float from one atom to another, thus allowing metals to conduct electricity.
