Roughly 75% of the atoms in the universe are hydrogen. This element is the most abundant in the universe due to its simplicity and ability to form various compounds.
Roughly 75% of the atoms in the universe are hydrogen.
Hydrogen and helium make up nearly 100 percent of the matter of the universe. Hydrogen comprises about 75 percent and helium makes up about 25 percent.
The molecular formula of sucrose is C₁₂H₂₂O₁₁. From this formula, we can see that there are 12 hydrogen atoms and 11 oxygen atoms in sucrose. Despite oxygen accounting for 51.5% of the mass and hydrogen only 6.4%, the ratio of hydrogen atoms to oxygen atoms is determined by the molecular formula, not the mass percentages.
Sulfur atoms are chemical elements with an atomic number of 16. They are commonly found in compounds like hydrogen sulfide and sulfuric acid. Hydrogen atoms are the simplest and most abundant atoms in the universe, with an atomic number of 1. They are commonly found in compounds like water and hydrocarbons.
In terms of the number of atoms it is 50%. In terms of mass, it is 5.88%.
Roughly 75% of the atoms in the universe are hydrogen.
While less than 5% of the universe is made up of atoms, hydrogen and helium make up 98% of the atoms in the universe.
The most abundant gas in the universe is hydrogen. Hydrogen atoms make up about 75% of the universe's elemental mass.
Hydrogen and helium make up nearly 100 percent of the matter of the universe. Hydrogen comprises about 75 percent and helium makes up about 25 percent.
They are about as old as the universe. In other word they are over 13 billion years old.
Hydrogen and helium make about 98% of the atoms in the solar system !

Sugar contains 6 percent of hydrogen content
The most common element in the universe is hydrogen.
No, Elements are the same everywhere in the Universe.
Most hydrogen atoms don't contain any neutrons. Deuterium atoms are hydrogen atoms with one neutron each, and tritium atoms are hydrogen atoms with two neutrons each, but most hydrogen atoms are protium atoms, with no neutrons at all. All other atoms in the universe except protium contain at least one neutron each.
When hydrogen and helium atoms first formed in the universe, the temperature ranged from about 3000 to 4000 Kelvin. This temperature allowed protons and electrons to combine to form neutral hydrogen atoms, a process known as recombination. Subsequently, the universe became transparent to radiation for the first time.
