Dictionary » E » Electronegative



(Science: chemistry, physics) Relating to or charged with negative electricity.

Normally refers to an element whose uncharged atoms have a tendency to ionise by adding electrons, thus becoming anions (e.g., oxygen, fluorine, chlorine).

It has the property of being attracted by an electropositive body, or a tendency to pass to the positive pole during electrolysis.

Re: Glycolysis - reductive/oxidative?

... due to swapping for more electron-donating substituents (reduction), or is the electron density of those carbons decreased due to bonding to more electronegative substituents (oxidation)?

Cell Respiration Question

... really confused here because there are many redox reactions in cellular respiration (take water, for example - it gets reduced, as the final most electronegative player in the electron transport chain) - if there are so many redox reactions in cellular respiration, how can you categorize cellular ...

... is caused when the electron of the H-atom is unequally divided over 2 atoms. Usually, H-bonds exist with N,O or F present as these are highly electronegative and 'absorbs' the electron of H to themselves. so a H-bond is similar with a polar bond. a protein is not like the structure of DNA!!! ...

The Fiber Disease

... upsets that control enzyme repairs and other processes within cells. Upsets in these trace metals occur due to the fact that fluorine is the most electronegative element and when present within the body will cease onto trace metals spontaneously. This effect keeps these trace metals from being ...

chemical in cells

haha...so you see my joke eh??:lol: here's the tips, water is H 2 O. because it contains O atom, this molecule is polar (O is more electronegative than H). And according to the principle "like dissolves like" we know that between polar molecules, they dissolves each other. It ...
