Explain what covalent bonds are and their role in combining atoms?

covalent bond is a type of bond between atoms in which the electrons are shared.


What is a covalent bond and its role in combining atoms?

A covalent bond is a bond that forms between two nonmetals in which the atoms share electrons in order for them both to have a perfect octet of valence electrons. It is the strongest type of intramolecular bond.


Explain the role of electrons in chemical bonding and in relation to the octet rule?

Electrons of an atom occupy areas of space called electron shells or energy levels. Electrons in the shell farthest from the nucleus are the most energetic. Chemical bonds are energy relationship between valence shell electrons of the reacting atoms. Atoms with eight valence shell electrons are chemically unreactive. Those with an incomplete valence shell interact with other atoms to achieve stability. There are 3 types of chemical bonds: ionic, covalent and hydrogen. Ionic bonds are formed when valence shell electrons are completely transferred from one atom to another. Covalent bonds are formed when atoms shared electron pairs. (Equal sharing called nonpolar molecule: unequal - polar). Hydrogen bonds are weak bonds formed between one hydrogen atom (already covalently linked to electronegative atom) and another electronegative atom (e.q. N, H, and O). They bind together different molecules (e.g. H2O) or different parts of the same molecule (e.q. protein molecules).


What role do valence electrons play in formation of bonds?

Valence electrons are electrons on the outermost "level". And depending on its electron configuration, it plays a role in which if the atom requires to gain or lose electrons in order to become "stable", it can accept or give electrons to another atom in a chemical reaction.


Is H a loss or gain of electrons in a ionic bond?

This is a trick question, since hydrogen does not form ionic bonds, only covalent bonds (or in some cases, what are called hydrogen bonds). But if you were to ask if hydrogen tends more toward being a donor of electrons (i.e., a metal) or a recipient of electrons (i.e., a non-metal) hydrogen tends to donate electrons. For example in water, H2O, all three atoms share the valence electrons (which is what makes this a covalent bond) however the electrons spend more time in the vicinity of the oxygen atom then they do in the vicinity of the two hydrogen atoms.I am going to make an addition to this answer. The element hydrogen, which is immensely important in organic chemistry, is almost always found as I described it, forming covalent bonds and having a metallic role, tending to donate electrons. However, there are other possible hydrogen compounds, such as lithium hydride (LiH) in which hydrogen does form an ionic bond, and in which it acts as an electron recipient rather than an electron donor. Hydrogen has an electronegativity that is intermediary between metal and non-metal, so it can take on either role. However, it is very rare to encounter lithium hydride, in comparison to compounds such as water, methane, ammonia, etc., in which hydrogen has the characteristics of a metal.

What bonds are in DNA and where are they found?

There are two types of bonds in DNA: phosphodiester bonds and hydrogen bonds. The phosphodiester bonds are the strong covalent bonds that create the phosphate-deoxyribose backbone. The hydrogen bonds links the "rungs" of the ladder, between nitrogen bases.


How are hydrogen bonds important in your body?

Hydrogen bonds are important to the body for several reasons. For one thing, they cause DNA to retain its double helix structure. Additionally, they contribute to the folding of proteins, which is necessary for proper protein function.


What is an electron's role in a polar molecule?

Polar bonds exist because certain atoms have a greater pull on the electrons in a bond than other atoms. The ability of an atom to attract electrons in a covalent bond is called "electronegativity". Atoms with a greater electronegativity will have a greater pull on the electrons in a bond than atoms with lower electronegativities. What this means for an electron is that it is not "shared" all that fairly. It will spend more time on the more electronegative atom than it will on the less electronegative atom (to a degree proportional to the difference in their electronegativity).


What is the role of an electron is an atom?

Electrons determine the ways in which atoms join together chemically, by forming bonds with other atoms. They also are carriers of electrical energy (current).

What is the meaning of hexakisphosphate?

Inositol Hexakisphosphate, commonly known as IP6 or phytic acid, is the principal storage mechanism of phosphorous in many species of plants. It has gained some popular attention recently due to some studies that indicate it may bear a role in preventing and treating cancer. It is formed with six oxygen molecules in the center all of which share a single covalent bond. Connected to each of the oxygen molecules by a single covalent bond is a phosphorous atom that is also connected to another oxygen molecule (two covalent bonds) and two (OH) molecules by a single covalent bond each. A diagram can be found on Wikipedia under Phytic acid.
