Why hydrogen diffuses four times more than helium?
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.
How much hydrogen and helium is on Saturn?
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 atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
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.
Which elements have the smallest atomic mass?
Hydrogen and Helium
Does hydrogen or helium have the least atomic mass?
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.
Is the The mass of 4 individual hydrogen atoms is more than the mass of 1 helium?
Yes.
What fraction of the mass in the known universe is made up of hydrogen and helium?
By mass, hydrogen = 75%, helium = 23%.
Which has the least number of atoms 5g of hydrogen or 10g of helium?
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.
Is the element with the least atomic mass hydrogen or is it helium?
The answer is Hydrogen.
Why hydrogen diffuses four times more than helium?
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.
What elements makes up most of the suns mass?
The main two are hydrogen and helium.
How much hydrogen and helium is on Saturn?
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.
What two elements make up most of the sun's mass?
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 atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
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.
Which elements have the smallest atomic mass?
Hydrogen and Helium
What is the element with the least atomic mass is hydrogen or helium?
Hydrogen's atomic mass (1 amu for the most stable isotope) is less than that of helium (4 amu).
Does hydrogen or helium have the least atomic mass?
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.
