Maternal bond
* are influenced by hundreds of emotional , mental and physical issues
  - emotional, mental and physical issues.
  * The term 'maternal bond' refers to bondings that often happen due to pregnancy issues and childbirth, or between women and unrelated children, such as with adoptions. Maternal bonds are influenced by hundreds of emotional, mental and physical issues. Some new mothers do not bond instantly, however. Some moms may have substandard mental conditions

Mechanical bond
* are subject to corrosion and physical damage.
* hold by surrounding object, then hardening.

Metallic bond
* are found in metals like zinc
  - omnidirectional
* occur between metal atoms
  - when electrons are shared among all the atoms

Molecular bond
* Most molecular bonds hold atoms
  - fluorine atoms
* vibrate at a particular frequency.

Municipal bond
* Many municipal bonds carry credit ratings issued by one of the major credit rating agencies.
* Most municipal bonds are free of federal income taxes on interest distributions.
* are a conservative way to increase assets steadily, tax free
  - good way to shelter income from tax
  - popular alternative to taxable bonds
* are debt obligations of state and local governments
  - securities issued by state and local governments
  - federal income tax free
  - generally exempt from federal taxes
  - one low-cost financing option available for municipal utilities
  - the debt obligations of state and local governments and their agencies
* come in a variety of forms.
* earn tax-free income.

Pair bond
* All pair bonds are heterosexual.
* Most pair bonds take places.
* are brief or absent
  - maintained for the life of both partners
* are strong, often permanent
  - persisting until one of the mates dies
* dissolve once the female begins incubation.
* last for several years
* remain strong until clutches are completed.
* tend to break up, however, when the female begins incubating eggs.

Peptide bond
* are amide links
  - chemical bonds
  - covalent bonds
  - the only covalent bond that can link together two amino acids in proteins
* assume the trans configuration.
* form, and anticodons bind to complementary codons.
* is planar and rigid.
* linking amino acids are susceptible to enzymatic attack.

Pi bond
* are harder to represent than signma bonds for obvious reasons
  - usually weaker than sigma bonds
* happen when two atomic orbitals are in contact through two areas of overlap
  - in contact through two areas of overlap. * in contact through two areas of overlap. Pi-bonds are more spread out bonds than the sigma bonds. Electrons in pi bonds are sometimes called 'pi electrons'. Molecular fragments joined by a pi bond cannot rotate about that bond without breaking the pi bond. The rotation destroys the parallel paths of the two p orbitals

Polar bond
* See polar covalent bond.
* are covalent bonds in which one of the atoms has a more negative charge than the other.
* create a dipole-dipole intermolecular force.
* happen when two atoms form a molecule using a covalent bond.

Salt bond
* are important type of chemical bonds in the hair.
* give hair many important properties and affect most chemical treatments.

Serial bond
* come due at different points in time.
* provide for the repayment of principal in a series of periodic installments.

Social bond
* Most social bonds occur between adult females and their dependent and weaned offspring.
* are maintained via grooming and sharing of food.
* develop among people working together as a group.
* enhance reproductive success in male macaques.

Special bond
* Most special bonds involve obligation.
* form between people who learn, work and play together.
