The atomic symbols of nitrogen and oxygen are N and O respectively the chemical formula of a particular substance is NO2 Which of the following is correct description of the substance a compound made up of one nitrogen atom and two oxygen atoms B, a compound made up of two nitrogen atoms, and two oxygen atoms see an element made up of two nitrogen atoms, and two oxygen atoms be an element made of one nitrogen atom, and one oxygen atom

The correct description of the substance is:

- a compound made up of one nitrogen atom and two oxygen atoms (NO2)

The correct description of the substance NO2 is:

A compound made up of one nitrogen atom and two oxygen atoms.

To determine the correct description of the substance with the chemical formula NO2, we need to understand the concept of chemical formulas and the atomic symbols of the elements involved.

The chemical formula provides information about the elements present in a compound or molecule and the ratio of atoms of each element. In this case, the chemical formula NO2 contains the atomic symbols N (nitrogen) and O (oxygen), indicating the presence of nitrogen and oxygen atoms.

Option A states that the substance is a compound made up of one nitrogen atom and two oxygen atoms. To verify if this is correct, we can count the number of atoms of each element in the chemical formula NO2. We find one nitrogen atom (N) and two oxygen atoms (O). Therefore, option A is the correct description of the substance.

Option B states that the substance is a compound made up of two nitrogen atoms and two oxygen atoms. However, the chemical formula NO2 does not contain two nitrogen atoms, as it only has one. Therefore, option B is incorrect.

Option C states that the substance is an element made up of two nitrogen atoms and two oxygen atoms. Elements consist of only one type of atom, so option C cannot describe a compound. Therefore, option C is incorrect.

Option D states that the substance is an element made of one nitrogen atom and one oxygen atom. However, the chemical formula NO2 contains only one nitrogen atom and two oxygen atoms. Therefore, option D is incorrect.

In conclusion, option A is the correct description of the substance as a compound made up of one nitrogen atom and two oxygen atoms.
