what is a bond
A bond is a debt investment in which an investor loans money to an entity (typically corporate or governmental) which borrows the funds for a defined period of time at a variable or fixed interest rate. Bonds are used by companies, municipalities, states and sovereign governments to raise money and finance a variety of projects and activities. Owners of bonds are debtholders, or creditors, of the issuer.
substances with different type of bonds
Metallic bonding arises from the electrostatic attractive force betweenconduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions. It may be described as the sharing of free electrons among a lattice of positively charged ions (cations). Metallic bonding accounts for many physical properties of metals, such asstrength, ductility, thermal and electrical resistivity and conductivity, opacity, andluster.[1][2][3][4]
Metallic bonding is not the only type ofchemical bonding a metal can exhibit, even as a pure substance. For example, elementalgallium consists of covalently-bound pairs of atoms in both liquid and solid state—these pairs form a crystal lattice with metallic bonding between them. Another example of a metal–metal covalent bond is mercurous ion(Hg2+
