Answer:
No.
Explanation:
If the concentration of nitrogen, oxygen and carbon increases to 97 % and the concentration of hydrogen and helium decreases by 3 %, then it is not considered as a star, it will be called a planet just like earth. The higher concentration of hydrogen and helium are responsible for the luminous characteristics of stars such as sun so if the concentration changes, the luminous intensity decreases that leads to formation of planet.
