Chemical Bonds

The atoms of elements of the periodic table are not often found as independent particles in nature, but are rather found in chemical bonds. But what is a chemical bond? A chemical bond is a mutual electrical attraction between the nuclei and valence electrons of different Atoms that binds the Atoms together. Otherwise meaning two atoms that have valence electrons that complement each other so they combine. When an atoms is unbonded it has a high potential energy and when the atom bonds to another atom the potential energy decreases making the pair more stable. When the atoms are bonded the valence electrons are redistributed in ways to make the atoms more stable. The way these electrons are distributed determines the type of bonding.

Ionic bonding

Ionic bonding is what results when cations and anions, or metals and non metals,  are electrically attracted and bond. In purely ionic bonding atoms completely give up electrons to other atoms. Ionic bonds can be identified by their properties shuch as  high melting and boiling point, crystalline as a solid, solubility in water and good conductor of electricity in a liquid state.

Covalent bonding

Covalent bonding often occurs when two nonmetals atoms are bonded. It differs from ionic bonding because the Atoms share their valence electrons. In a purely covalent bond the electrons are equally owned by the two bonded atoms. Covalent bonds are characterized by lower melting and boiling points, poor electrical conduction in all phases and solubility in water.

Metallic bonds

Metallic bonding occurs when two metals are electrically attracted metallic bond similarly to covalent bonds have valence electrons that they share. Metallic bonds have characteristics such as ductility, luster, good conduction of heat and electricity in all States of matter and high melting and boiling point.
