Which of the following is the most abundant element in universe?
Show Hint
Hydrogen makes up about three quarters of ordinary matter by mass.
Updated On: Oct 1, 2026
- \(\text{H}\)
- \(\text{O}\)
- \(\text{Ne}\)
- \(\text{C}\)

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Abundance in the universe is set by how elements were formed. Stars and the early universe made mostly the lightest elements.
Step 2: Detailed Explanation
Hydrogen is by far the most abundant element, about 75 percent of the visible mass of the universe, followed by helium at about 24 percent. Oxygen, carbon and neon are far less abundant. Oxygen is the most abundant element in the Earth crust, which is a different question.
Final Answer:
Hydrogen is the most abundant element in the universe, option (A). \[ \boxed{\text{H}} \]
