A 'secured' bond is one for which money and/or property has actually been deposited to ensure the appearance of the defendant. An "unsecured" bond is one in which money and/or property has been 'promised' to ensure the same result.
A bail bond is a security to make sure you go to court, a bank bond is a bond you can cash out, or a bank bond is also a bond that a teller has to have to secure their job if they should lose money.
The performance bond is what you might get depending on interest rates. The bank guarantee is more secure and will be guaranteed money regardless of what the economy does.
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
The type of bond that forms between atoms or compounds is determined by the electronegativity difference between the atoms involved in the bond. If the electronegativity difference is small, a covalent bond forms, where electrons are shared. If the electronegativity difference is large, an ionic bond forms, where electrons are transferred.
Some general rules are:- the difference between the electronegativities of two atoms is over 2: ionic bond- the difference between the electronegativities of two atoms is in the range 0 -2: covalent bond- the difference between the electronegativities of two atoms is approx. zero: polar covalent bond
When the difference in electronegativity between atoms is 0.9, a polar covalent bond exists.
The bond formed is nonpolar covalent if the difference in electronegativity between two atoms is between 0 and 0.5. This means that the electrons are shared equally between the atoms in the bond.
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.
Electronegativity is a measure of an atom's ability to attract shared electrons in a chemical bond. In general, the greater the electronegativity difference between two atoms in a bond, the more polar the bond. A higher electronegativity difference between two elements in a bond typically results in an ionic bond while a smaller difference leads to a covalent bond.
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. Please refer to the related links.
If the difference in electronegativity between the metal and the non metal is above 1.7, then ionic bond is formed. If the difference in electronegativity between the metal and the non metal is below 1.7, then polar covalent bond is formed.
The strength of the chemical bond between the two atoms increases as the electronegativity difference between them increases. A higher electronegativity difference leads to a more polar bond, resulting in a stronger attraction between the positively-charged and negatively-charged ends of the bond.
