Question

What is the most abundant element in the universe?

Answer 1

The most abundant element in the universe is Hydrogen, which makes up about 74% of the universe's elemental mass.

Hydrogen is the lightest element and the most abundant element in the universe. It is found in stars, galaxies, and many other cosmic objects. Hydrogen is also the most abundant element in the Earth's atmosphere, making up about 75% of the air we breathe. Hydrogen is a key component of water, which is essential for life on Earth.

Answer 2

The most abundant element in the universe is hydrogen. It makes up about 74% of the mass of the visible universe. Helium is the next most abundant element, making up around 24% of the universe's mass. The remaining 2% is made up of all other elements combined, including oxygen, carbon, and iron. Hydrogen is the main fuel for stars, and it is also present in planets and moons, though in much smaller amounts. Its abundance in the universe has important implications for understanding cosmic evolution and the formation of galaxies.

Answer 3

The most abundant element in the universe is hydrogen. It is estimated that hydrogen makes up about 74% of the total mass of the observable universe, followed by helium with around 24%. Other elements like carbon, oxygen, and iron are present in much smaller quantities. Hydrogen is also the most abundant element in the Earth's atmosphere, oceans, and crust, and plays a critical role in various chemical and physical processes.

Answer 4

The most abundant element in the universe is hydrogen. It forms about 75% of the baryonic mass of the universe, which includes all ofthe matter that we can see, feel, and detect with our instruments. Helium is the next most abundant element, making up about 23% of the baryonic mass.
