Which of the following gases is found in very little qantity in the atmosphere?

Argon is found in very little quantity in the atmosphere. The Earth's atmosphere is composed of different gases, and they are present in varying amounts. The most abundant gas in the atmosphere is nitrogen, which makes up about 78% of the atmosphere. Oxygen is the second most abundant gas, making up about 21% of the atmosphere. Carbon dioxide, although a minor component, plays an essential role in the greenhouse effect, which helps to regulate the temperature of the Earth. Argon, on the other hand, is a noble gas that is chemically inert and does not react with other substances. It is present in the atmosphere in very small quantities, about 0.93%, making it one of the least abundant gases in the atmosphere. Argon is mostly obtained through the process of fractional distillation of liquid air, where it is separated from other gases such as nitrogen and oxygen.
