Question

a)In what form does oxygen gas occur in nature?
b)In what form do noble gases occur in nature?

Answer 1

Hint: First of all we have two options. So first we will know about oxygen and its discovery. Then we will find out in which form it exists in nature. Next we will talk about noble gas and why they are called noble gas. Then we will find that in what form they occur in nature and also will know about the reason.

Complete step by step solution:
Step1. Oxygen is a gas found on earth in abundance. It’s atomic number is and its symbol is .It is a member of the Chalcogen family. It is very reactive and it is a very strong oxidizing agent. It constitutes almost all of the earth's atmosphere.
Step2. The oxygen is found in diatomic nature in a free atmosphere. But when it comes to water it is present in the compound form in water and glucose. It is often found in the form of .It is present in diatomic nature because oxygen is a reactive atom so it is more stable when it is in the diatomic nature.
Step3. Noble gases are also called inert gases. They all depict similar properties. They are called inert gases because they don’t react with any compound in normal conditions. They have a completely fulfilled shell. So electrons don’t come out of the shell easily. They start from helium and end with Radon.
Step4. The noble gases are present in a monatomic state. They are highly stable and they do not form in diatomic form.

Note: The helium is very light and non-flammable. It is very safe to use it in the balloons. Most of the noble gases were discovered by Sir William Ramsay. All the noble gases except for radon have stable isotopes.
