Covalent Bond Force holding atoms in a molecule together as a specific, separate entity (as opposed to, e.g., colloidal aggregates; see bonding). In covalent bonds, two atoms share one or more pairs of valence electrons to give each atom the stability found in a noble gas. In single bonds (e.g., H-H in molecular hydrogen), one electron pair is shared; in double bonds (e.g., O=O in molecular oxygen or H2C=CH2 in ethylene), two; in triple bonds (e.g., HCºCH in acetylene), three. In coordinate covalent bonds, additional electron pairs are shared with another atom, usually forming a functional group, such as sulfate (SO4) or phosphate (PO4). The number of bonds and the atoms participating in each (including any additional paired electrons) give molecules their configuration; the slight negative and positive charges at the opposite ends of a covalent bond are the reason most molecules have some polarity (see electrophile; nucleophile). Carbon in organic compounds can have as many as four single bonds, each pointing to one vertex of a tetrahedron; as a result, certain molecules exist in mirror-image forms (see optical activity). Double bonds are rigid, leading to the possibility of geometric isomers (see isomerism). Some types of bonds, such as the amide linkages that join the amino acids in peptides and proteins (peptide bonds), are apparently single but have some double-bond characteristics because of the electronic structure of the participating atoms. The configurations of enzymes and their substrates, determined by their covalent bonds (particularly the peptide bonds) and hydrogen bonds, are crucial to the reactions they participate in, which are fundamental to all life. http://www.answers.com/topic/covalent-bond?cat=health

What type of bond hold H2O atoms together?
A covalent bond holds the H2O atoms together. In a water molecule, oxygen and hydrogen atoms share electrons to form covalent bonds, resulting in a stable compound.
Is chlorophyll an ionic or a covalent bond?
Chlorophyll makes a covalent bond, as the elements it is made from, hydrogen, chlorine and carbon, all need what the others have and so they form a covalent bond
What type of bonds are in organic compounds?
Organic compounds typically contain covalent bonds. These bonds involve the sharing of electrons between atoms to form a stable molecular structure. Covalent bonds are commonly found in organic molecules due to the need to achieve a stable electron configuration.
What determines the number of covelant bonds that an atom can form?
The number of covalent bonds that an atom can form is determined by the number of valence electrons it has. Atoms will typically form covalent bonds in order to achieve a full outer shell of electrons (octet rule). The number of covalent bonds an atom can form is related to the number of electrons needed to achieve this stable electron configuration.
How many convalent bonds will an oxygen atom form with hydrogen atom?
It'll form either one (if something else is bonding to the oxygen atom) or two (if you're making water, in which case you need two hydrogen atoms).
Need an example of covalent bonds?
Any molecule with two non metal atoms (HCl, HF or O2 as examples) form a covalent bond between the bonding atoms.
Why do atoms need to form covalent bonds or become ions?
Because they need 8 valecne electorns, and some don't so they share or transfer. :)
What type of bond hold H2O atoms together?
A covalent bond holds the H2O atoms together. In a water molecule, oxygen and hydrogen atoms share electrons to form covalent bonds, resulting in a stable compound.
How many chlorine atoms would a silicone atom need to form with it so that the silicone is stable?
A silicon atom does not typically form covalent bonds with chlorine atoms. Silicon is more likely to form bonds with oxygen atoms to create silicon dioxide (SiO2) or silicates. These compounds are stable due to the strong bonds formed between silicon and oxygen atoms.
Is chlorophyll an ionic or a covalent bond?
Chlorophyll makes a covalent bond, as the elements it is made from, hydrogen, chlorine and carbon, all need what the others have and so they form a covalent bond
What kind of bond holds together the atoms within the molecule?
Chemical bonds hold together the atoms within a molecule. The most common types of chemical bonds are covalent bonds and ionic bonds. Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another.
What type of bonds are in organic compounds?
Organic compounds typically contain covalent bonds. These bonds involve the sharing of electrons between atoms to form a stable molecular structure. Covalent bonds are commonly found in organic molecules due to the need to achieve a stable electron configuration.

How do you know that sulfur and carbon form a covalent bond?
Nonmetals, such as sulfur and carbon, tend to form covalent bonds with one another. Also, the difference in electronegativity between sulfur and carbon is 0.03, which means they form a nonpolar covalent bond with one another.
How many convalent bonds will an oxygen atom form with hydrogen atom?
It'll form either one (if something else is bonding to the oxygen atom) or two (if you're making water, in which case you need two hydrogen atoms).
Is sulphur and carbon an ionic or a covalent bond?
A bond between sulphur and carbon is covalent. In covalent bonds, atoms share electrons to achieve a stable electron configuration. Ionic bonds involve the transfer of electrons between atoms of different electronegativities.
What happens when atoms form a covalent bond?
a) Must include a metal and a nonmetal b) Must be of different elements c) Are always of the same element d) Are always two metals Need Answer! :( D) Are always two metals. a) is for ionic compounds b) is for nonpolar covalent bonds c) same as nonpolar covalent bonds b) Must be of different elements:)
