Helium has more mass than hydrogen.
Hydrogen has a smaller atomic size and lower atomic mass compared to helium, allowing it to move faster and diffuse more rapidly. Additionally, hydrogen has a higher kinetic energy at a given temperature, which also contributes to its increased diffusion rate.
Saturn is primarily composed of hydrogen and helium. It is estimated that about 75-90% of Saturn's mass consists of hydrogen, while helium makes up most of the remaining mass, along with traces of other elements.
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
Hydrogen and Helium
Hydrogen has the lowest atomic mass of all the elements. Hydrogen has one proton and one electron. Helium, two neutrons, two protons and two electrons.
Yes.
By mass, hydrogen = 75%, helium = 23%.
10g of helium has fewer atoms. This is because the atomic mass of helium is much higher than that of hydrogen, so the same mass of helium contains fewer atoms than the same mass of hydrogen.
The answer is Hydrogen.
Hydrogen has a smaller atomic size and lower atomic mass compared to helium, allowing it to move faster and diffuse more rapidly. Additionally, hydrogen has a higher kinetic energy at a given temperature, which also contributes to its increased diffusion rate.
The main two are hydrogen and helium.
Saturn is primarily composed of hydrogen and helium. It is estimated that about 75-90% of Saturn's mass consists of hydrogen, while helium makes up most of the remaining mass, along with traces of other elements.
Hydrogen and helium make up the majority of the sun's mass, with hydrogen accounting for about 74% and helium for about 24%. Other elements like oxygen, carbon, and nitrogen make up less than 2% of the sun's mass.
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
Hydrogen and Helium
Hydrogen's atomic mass (1 amu for the most stable isotope) is less than that of helium (4 amu).
Hydrogen has the lowest atomic mass of all the elements. Hydrogen has one proton and one electron. Helium, two neutrons, two protons and two electrons.
