Patriot Bonds are Series EE savings bonds, which are specially inscribed with the words "Patriot Bond." The Patriot Bond series will begin December 11, 2001. Bonds increase in value every month, and interest is compounded semiannually. You can cash your bond after six months. Bonds cashed before they are five years old are subject to a 3-month interest penalty.
If there is a slight electronegativity difference, the bond is a nonpolar covalent bond. If there is a large electronegativity difference, it is an ionic bond. If the difference is somewhere between, it is a polar covalent bond.
Ionic bond: the difference between electronegativities of the atoms is over 2.Covalent polar bond: the difference between electronegativities of the atoms is under 2.Covalent non-polar bond: the difference between electronegativities of the atoms is cca. zero
Ionic bond: involve an electrostatic attraction between atoms.Covalent bond: electrons are shared between atoms.
Peptide bond is the bond formed between amino acids. Glycosidic bond is the bond formed between simple sugars Peptide bond is the bond formed between amino acids. Glycosidic bond is the bond formed between simple sugars
The major difference between a bond and a promissory note is that a bond has longer maturity terms. Also, a bond is released in a stamped, certified and official series. A promissory note is made on an individual basis and specifies the terms of the loan including interest and maturity date.Second, bonds are released in an official, stamped and certified series, each bond being for a similar amount and on similar terms, while promissory notes are made on an individual basisRead more : http://www.ehow.com/about_6516863_comparison-bond-vs_-promissory.html
If the electronegativity difference between two atoms is less than 1.7, then a covalent bond is formed between the two atoms.
It depends on the difference in electronegativity between the two atoms. If the EN difference between two atoms is less than 0.5,the bond is nonpolar covalent. If the EN difference between the two atoms is between 0.5 and 1.6, the bond is polar covalent. If the EN difference between the atoms is greater than 2.0, the bond is ionic. If the EN difference is between 1.6 and 2.0, and if a metal is involved, then the bond is considered ionic. If only nonmetals are involved, the bond is considered polar covalent.

Yankee is an American Bond, while Bulldog is a British Bond.
Shaken not stirred.
If this difference is under 2 the bond is covalent; if the difference is over 2 the bond is ionic.
