volatility， polarizability， viscosity， electronegativity & hydrogen bonding

	A.	volatility
	B.	polarizability
	C.	viscosity
	D.	electronegativity
	E.	hydrogen bonding

 

以下是每个选项的定义，包括中文和英文：

A. 挥发性 (Volatility)

   - 定义：挥发性是指物质从液态转变为气态的趋势或速度。更挥发性的物质在给定条件下更容易转化为气体。
   - Definition: Volatility refers to the tendency or speed at which a substance transitions from a liquid to a gas. More volatile substances convert to a gas more readily under given conditions.

B. 极化性 (Polarizability)

   - 定义：极化性指的是分子内的电子云在外部电场作用下被扭曲或移位的程度。极化性较高的分子更容易受到外部电场的影响。
   - Definition: Polarizability refers to the degree to which the electron cloud within a molecule can be distorted or shifted under the influence of an external electric field. Molecules with higher polarizability are more susceptible to the effects of external electric fields.

C. 粘度 (Viscosity)

   - 定义：粘度是液体的内部阻力或黏性，即液体抵抗流动的能力。高粘度液体更难流动，而低粘度液体更容易流动。
   - Definition: Viscosity is the internal resistance or stickiness of a liquid, i.e., the liquid's resistance to flow. Liquids with high viscosity are less prone to flow, whereas liquids with low viscosity flow more easily.

D. 电负性 (Electronegativity)

   - 定义：电负性是一个原子吸引共享电子对的能力的度量。较高电负性的元素更强烈地吸引共享电子对，通常是在化学键中的共价键。
   - Definition: Electronegativity is a measure of an atom's ability to attract shared electron pairs. Elements with higher electronegativity tend to attract shared electron pairs more strongly, typically in covalent bonds.

E. 氢键 (Hydrogen Bonding)

   - 定义：氢键是一种特殊的非共价相互作用，其中氢原子与高电负性原子（通常是氧、氮或氟）之间的吸引力导致分子之间的强相互作用。氢键是由氢原子与这些高电负性原子之间的电荷分布产生的。
   - Definition: Hydrogen bonding is a special type of non-covalent interaction in which the attraction between a hydrogen atom and a highly electronegative atom (typically oxygen, nitrogen, or fluorine) leads to strong interactions between molecules. Hydrogen bonds arise from the charge distribution between the hydrogen atom and these electronegative atoms.
