Difference Between Ionic and Covalent

What is the primary difference between an ionic and a covalent bond?

Covalent bond creates compounds because the electrons are being shared to fill the octet, whereas in ionic bonds, ions are created as electrons donate/accept electrons to fill their octet

To add on, ionic bonds form lattices(salts) as products that tend to be soluble in water while covalent bonds form molecules that are less soluble in water.

Ionic bonds: noncovalent bonds (do not share electrons but transfer electrons), electronegativity difference: (X<0.5 is nonpolar; 0.5-1.7 is polar)

Covalent bonds: share electrons between two atoms, electronegativity difference: (X>1.7 is ionic)

The main difference between ionic and covalent bonds are the types of atoms that form the bonds. Ionic bonds are bonds between a metal and a non metal. For ionic bonds one atom will donate an electron to the other atom. Covalent bonds are bonds between two non metals. In covalent bonds the atoms are bound by shared electrons. Another big difference between covalent and ionic bonds is polarity. Ionic bonds have high polarity while covalent bonds have low polarity.

Ionic bonds are done between nonmetals and metals, while covalent bonds are formed between two nonmetals. Covalent is sharing, while ionic is donating.

Ionic bonds occur after electrons have been completely transferred over while covalent bonds are the sharing of ekectrons.

An ionic bond is a bond that is shared between a metal and a non-metal. These metals can also be referred to as ions (atom/molecule that loses or gains an electron). Ions that gain an electron (have a negative charge) are known as anions and those that lose electrons (positively charged) are cations. These opposite ions are attracted to each other and donate electrons in order to form an ionic bond.

A covalent bond is a bond that's shared between two non-metals. Unlike ionic bonds, which donate electrons, covalent bonds are formed with atoms that share one or more electron pairs.

Ionic bonds are bonds between a metal (cation) and a nonmetal (anion) and the cation donates the electron to the anion because of the large difference in electronegativity and ionization energy. Meanwhile, covalent bonds are between two nonmetals and they share the electron(s) by the electron transferring back and forth between the atomic orbits. Though covalent bonds do have polarity in some cases, it is relatively minimal compared to the high polarity of ionic bonds.
