9.Let's look at the differences inelectronegativitybetween sodium and chlorine. 让我们看看钠和氯之间的电负性差异。机翻 「可汗学院:学」评价该例句:好评差评指正 Crash Course 综合篇 10.That, along with the difference in electronegativities of oxygen and hydrogen, leads to the polarity of water and...
If you know the electronegativity of each atom in a diatomic molecule, you can predict how the bond will polarize. For example, on the Pauling Scale, hydrogen's electronegativity is 2.18 and chlorine's is 3.16. This results in a polar covalent bond, with hydrogen slightly positively charged a...
16.The electronegativity of the nonmetals is greater than that of hydrogen. 17.If, on the other hand, the atom E has a relatively high electronegativity, it strongly attracts the electrons it shares with the oxygen atom, making bond a relatively strongly covalent. ...
Covalent Bonding and Electronegativity Many biologically important compounds result from the combination of nonmetals on the right side of the periodic table - elements like carbon, hydrogen and oxygen make up carbohydrates, fats and nucleic acids, for example. These compounds are created by bonding,...
forming chloroacetic acid (ClCH2COOH), the electrons in the molecule are attracted to the chlorine because of its relatively high electronegativity; the bond between the hydrogen and the oxygen in the carboxyl group is thereby weakened through inductive effects and the degree of ionization in water...
Define electronegativity. electronegativity synonyms, electronegativity pronunciation, electronegativity translation, English dictionary definition of electronegativity. n 1. the state of being electronegative 2. a measure of the ability of a specified a
This means that the electron pair spends more time with the chlorine atom than with the hydrogen atom and thus chlorine is more electronegative than hydrogen. Nonmetals have much higher electronegativities than metals; of the nonmetals, fluorine is the most electronegative, followed by oxygen, ...
Indeed, bond type, material character and chemical reactivity can be predicted from a knowledge of electronegativity.For example, consider:Hydrogen chloride, HCl. Chlorine, 3.16, is more electronegative than hydrogen, 2.20, so the H–Cl bond will be polarised Hδ+–Clδ–. (This is pronounced ...
between hydrogen and oxygen that forms the water. This bonding which is highly affected by electronegativity is something that holds it together. Oxygen with its high electronegativity and hydrogen with its high electropositivity tends to hold each other together resulting in the formation of water. ...
