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 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 covalent bonds are and their role in combining atom?

What is the role of a chemical bond in a energy transfers?
The amount of energy required to break a bond and produce neutral atoms is called the bond energy. It harbors the energy.
How does an ionic bond hold molecules together?
Ionic bond is due to the electromagnetic force attracting particles (ions in chemical terms) with charges of opposite sign. The ionic bond is the stronger bond that is present in chemistry after covalent bond. It is sufficient to consider the fact that a simple calculation of the electrostatic energy related to two atoms carrying a point charges of +/- 3 atomic units (that is +/- 4.8 10-20 C) at a distance of 1 nm gives a bond energy of 2.1 10-20 J, that corresponds to about 12.54 kJ/mole: a quite substantial energy for two so small charges. This energy critically depends on distance and, in case of distributed charges, on the bond geometry. An example of material that is built by ionic bonds is table salt, essentially a set of NaCl dispersed micro-crystals, where each crystal is constructed by the ionic attraction among Na+ and Cl- ions. The bond with which antibodies attaches to their specific antigens carrying out their role in human immunity system is frequently dominated by a ionic component.
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 is the role of electrons in the formation of covalent bonds?
The outer shell electrons of the atom form covalent bonds.
What is covalent bond?
a type of strong chemical in which two atoms share one or more pairs of valence electons
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 type of bond is likely between atoms that are far apart on the periodic table?
Much the same as for other atoms. Differences in atomic number play no role.
What is the role of a chemical bond in a energy transfers?
The amount of energy required to break a bond and produce neutral atoms is called the bond energy. It harbors the energy.
How does electronegativity play a role in bonding?
Electronegativity (EN) is a property calculated from Ionization Energy and Electron Affinity. If EN difference is more than 1.7 , it is considered IONIC bond and less than that it is categorized as COVALENT bond. Again, it is not a phenomenon that is observed that plays a role but a value calculated. HOpe this helps.
3 elements common to all organic molecules?
All organic molecules are comprised of covalent bonds between hydrogen atoms and carbon atoms. There are many other elements that play a role in modifying the structure of organic molecules, such as oxygen, phosphorous, and nitrogen.
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.
What part of an organism have a major role in living things function properly?
The part of an organism that has a major role in helping living things function properly are the molecules. Molecules are formed when at least two atoms come together and form a chemical bond.
