Types of Molecular Bonds
Covalent Bond Definition. A covalent bond is a chemical link between two atoms or ions where the electron pairs are shared between them. A covalent bond may also be termed a molecular bond. Covalent bonds form between two nonmetal atoms with identical or relatively close electronegativity values.
In polar bonds, the molecular bond is unevenly shared between atoms; in non-polar bonds, the electrons are evenly shared between the two atoms. Features Molecular bonds are classified as either singular bonds or multiple bonds. Molecular bonds form single bonds, where two atoms only share one pair of electrons.
A high-yield bond is a high paying bond with a lower credit rating than investment-grade corporate bonds, Treasury bonds and municipal bonds. Because of the higher risk of default, these bonds pay a higher yield than investment grade bonds.
Hydrogen bonding: Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.
An investment grade is a rating that indicates that a municipal or corporate bond has a relatively low risk of default. Bond rating firms, such as Standard & Poor's and Moody's, use different designations consisting of upper- and lower-case letters 'A' and 'B' to identify a bond's credit quality rating.
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Municipal bonds are debt obligations issued by states, cities, counties and other governmental entities, which use the money to build schools, highways, hospitals, sewer systems, and many other projects for the public good.

Polar covalent bonds form between atoms with an electronegativity difference between 0.4 and 1.7. Examples of Molecules with Polar Covalent Bonds. Water (H 2 O) is a polar bonded molecule. The electronegativity value of oxygen is 3.44, while the electronegativity of hydrogen is 2.20.
BREAKING DOWN 'Treasury Bond - T-Bond' Treasury bonds (T-bonds) are one of four types of debt issued by the U.S. Department of the Treasury to finance the government’s spending activities. The four types of debt are Treasury bills, Treasury notes, Treasury bonds and Treasury Inflation-Protected Securities (TIPS).
