Ozone's O 3 structure was determined in 1865. The molecule was later proven to have a bent structure and to be weakly diamagnetic. At standard temperature and pressure, ozone is a pale blue gas that condenses at cryogenic temperatures …

2024年6月20日 · Ozone (O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth's upper atmosphere. (the stratosphere) and lower atmosphere (the troposphere). Depending on where it is in the atmosphere, ozone affects life on Earth in either good or bad ways.

臭氧 （英語： ozone）即 三氧 （trioxygen， 化学式：O 3），是 氧 的 单质 三原子分子，是 氧气 （双氧）的 同素异形体，在 常温 下是一种有刺鼻味道的淡蓝色 气体。 臭氧的 英语 称呼源自 希腊语 的中性现在时分词 ozein (ὄζειν)，意为“嗅”。 臭氧主要存在于距 地球 表面20公里的 平流层 下部的 臭氧层 中，含量約50ppm，主要由日光中的 紫外线 照射双氧产生 光解 而成，少量由 大气层 中的 放电 现象（闪电） 电解 产生。 臭氧是一种比氧气更活跃的 氧化剂，能吸收对 生物 细胞 …

2025年2月4日 · Ozone (O 3) is a gas molecule composed of three oxygen atoms. Ozone is good up high, bad nearby. The ozone layer found high in the upper atmosphere shields us from much of the sun's ultraviolet radiation. However, ozone air pollution at ground level where we can breathe it causes serious health problems.

臭氧，化学式为O3，又称三氧、超氧，因其类似鱼腥味的臭味而得名，在常温下可以自行还原为氧气。 比重比氧大，微溶于水，易分解。 臭氧由氧分子携带一个氧原子，因此它只是一种暂存状态，携带的氧原子除氧化用掉外，剩余的又组合为氧气进入稳定状态，所以臭氧没有二次污染。 [5] 臭氧主要是由 氮氧化物 (NOx)和 挥发性有机物 (VOCs)经过一系列复杂的光化学反应生成。 [6] 臭氧密度2.144 g/l（气）、1.614 g/ml（液，-185.4℃），熔点-192.7℃，沸点-111.9℃，临界温 …

2024年9月23日 · Ozone is a gas made up of three oxygen atoms (O 3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun’s ultraviolet (UV) radiation.

Ozone is an elemental molecule with formula O3. An explosive, pale blue gas (b.p. -112℃) that has a characteristic, pungent odour, it is continuously produced in the upper atmosphere by the action of solar ultraviolet radiation on atmospheric oxygen.

2025年1月23日 · Ozone is a triatomic allotrope of oxygen (a form of oxygen in which the molecule contains three atoms instead of two as in the common form) that accounts for the distinctive odor of the air after a thunderstorm or around electrical equipment. It is an irritating pale blue gas that is explosive and toxic.

2024年11月7日 · O3 gas is ozone, a colorless and odorless gas composed of three oxygen atoms. It naturally occurs in the Earth's atmosphere, both in the upper stratosphere and at ground level in the troposphere.

2025年1月5日 · O3, also known as ozone, is a gas composed of three oxygen atoms. It is a highly reactive and potent oxidizer, with a unique structure that plays a crucial role in various industrial, medical, and environmental applications.
