Question: 1 / 400

What is the most abundant element in the universe?

Hydrogen

The most abundant element in the universe is hydrogen. This is because hydrogen is the first element to be formed after the Big Bang, and it makes up about 75% of the universe's mass. Carbon, helium, and oxygen are also important elements in the universe, but they are not as abundant as hydrogen. While carbon is essential for life on Earth, it only makes up a small percentage of the universe's mass. Similarly, helium and oxygen are important elements, but they are not as abundant as hydrogen in space. Therefore, A is the correct answer for the most abundant element in the universe.
