溶液, 混合物

Many cleaning products are solutions that mix different liquids for better effectiveness.

许多清洁产品是混合不同液体以提高效果的溶液。

溶剂, 溶媒

Ethanol is commonly used as a solvent to dissolve oils and perfume essences for the production of aftershaves and colognes.

乙醇通常用作溶剂溶解油和香水精华，用于生产须后水和古龙水。

周期表, 元素周期表

The periodic table, devised by Dmitri Mendeleev, categorizes elements into rows and columns based on their properties.

由德米特里·门捷列夫设计的周期表根据元素的性质将它们分类为行和列。

同位素, 同位素形式

Carbon-12 and carbon-14 are isotopes of carbon, with the former having 6 neutrons and the latter having 8 neutrons.

碳12和碳14是碳的同位素，前者有6个中子，后者有8个中子。

卤素, 卤族元素

Chlorine is a halogen commonly used in water treatment for its disinfectant properties.

氯是一种卤素，因其消毒特性而常用于水处理。

惰性气体, 稀有气体

Helium, a noble gas, is known for its low density and is often used in balloons to make them float.

氦气是一种惰性气体，以其低密度而闻名，常用于气球中使其漂浮。
