Oxygen, the next most electronegative element, is also a powerful oxidant, as are chlorine and bromine. |
|
For example, electrons in a covalent bond are assigned to the more electronegative atom. |
|
Use hydrogen and halogens as terminal atoms and then use the least electronegative atom as the central atom. |
|
The boiling points decrease as the size of the electronegative atom decreases from hydrogen telluride to hydrogen sulfide. |
|
The centers of corresponding ellipsoids are close, in agreement with well-known restrictions on the hydrogen bonding of electronegative atoms. |
|
These rules are the result of assigning all electrons in a covalent bond to the more electronegative atom in the bond. |
|
Because halogens are highly electronegative, their atoms normally retain negative charge in these compounds. |
|
The less electronegative atom will have a partial positive charge since the shared electrons spend less time near it. |
|
Because iron has an affinity electronegative atoms such as oxygen, nitrogen and sulfur, these atoms are found at the heart of the iron-binding centers of macromolecules. |
|
Consequently, the more electronegative atom has a partial negative charge. |
|
Specifically, large electropositive or electronegative regions can reasonably attract oppositely charged entities through long-range electrostatic interactions. |
|
Also, the energy has such a large negative value, because the cholesterol hydroxyl interaction with the phosphate group involves several electronegative phosphate oxygens. |
|
That makes lead dioxide much more electronegative than classical theory would predict. And so it turned out. |
|
Lead dioxide, on the other hand, is highly electronegative, preferring to absorb electrons in chemical reactions. |
|
Fluorine is an halogen and it is the most electronegative of all the elements, so it reacts easily with most of the elements. |
|
Perfluorinated substances are also intrinsically polar chemicals because fluorine, a highly electronegative element, imparts polarity. |
|
Fluorine is the most electronegative atom. As such it creates strong dipoles, causing molecules to react to external electric fields. |
|
It is the non-metallic element the most chemically active of all the elements and it also has the most unstable electronegative ion. |
|
Thus, it seems generally accepted that zinc is more electronegative than magnesium and, similarly, that gallium is more electronegative than aluminum. |
|
An interionic bond forms when a highly electropositive metal ion is combined with a highly electronegative non-metal ion. |
|
|
The drug aerosols cloud emitted by Albuterol and Ventolin were determined to be electropositive while Atrovent and Qvar were electronegative. |
|
Some covalently bonded hydrides have a hydrogen atom bound simultaneously to two separate electronegative atoms, which are then said to be hydrogen bonded. |
|
The highly electronegative fluorine substituent stabilizes this intermediate much more than do the other halogens and causes it to be formed faster. |
|
Our results show that the most electronegative area of the urate molecule is the N3 site which has the strongest affinity for metal cations. |
|
Hydrogen also forms compounds with less electronegative elements, such as metals and metalloids, where it takes on a partial negative charge. |
|
These polar side groups usually contain electronegative atoms from groups 5 through 7 in the periodic table. |
|
Fluorine is the most electronegative and reactive of all elements and therefore in nature, it does not exist in the free state but always forms compounds. |
|
Electronegative low density lipoprotein subform is increased in patients with short-duration IDDM and is closely related to glycaemic control. |
