Which is heavier hydrogen or helium?
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
What happens after the hydrogen transform into helium?
During nuclear fusion, hydrogen atoms combine to form helium, releasing a large amount of energy in the process. This energy is what powers the sun and other stars, contributing to light and heat production. After hydrogen transforms into helium, other elements can be formed through further fusion reactions in the star's core.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe. They were created during the Big Bang and continue to play a vital role in the composition of stars and galaxies.
What are the two main elements of the sun?
The two main elements in the sun are hydrogen and helium. Hydrogen is the most abundant element in the sun, making up about 74% of its mass, while helium accounts for about 24%.
What is something mostly hydrogen some helium?
A star is mostly composed of hydrogen and some helium. The fusion of hydrogen into helium is what produces the energy and light that stars emit.
What happens when hydrogen and helium mix?
Helium is completely inert, it is the most inert of all elements, and so it will not react in any way with hydrogen (or with any other element). So, if you mix hydrogen and helium, nothing happens. You have a mixture of hydrogen and helium. It's a lot lighter than air, you can make balloons that will float. Of course, you can do that with pure hydrogen or with pure helium, as well.
What does the element vanadium mix with?
Oxygen, Hydrogen and Helium.
Why helium is better than hydrogen for balloons?
because helium does not mix with other elements
What nuclear reaction happens between hydrogen and helium in the sun?
Nuclear fusion, in which hydrogen-1 is fused into helium-4.
How does the sun actually product energy?
hydrogen particles mix with helium particles
What are the symbols for hydrogen and helium?
The symbol for hydrogen is H, and the symbol for helium is He.
What are the two main elements found in the stars?
Hydrogen and helium
Can you make hydrogen from other chemicals?
Yes you can make hydrogen from water through electrolysis. And also from helium (this happens in the sun)
What happens to the attraction between particles in a nebula as it begins to collapse?
helium and hydrogen gases
Hydrogen and helium formulas?
Hydrogen is H2. Helium is He.
What is the atmosphere of Saturn like on Saturn?
it is dense mix of Hydrogen and trace gases ( like Helium, Methane, Ammonia)
What happens if you mix hydrogen with oxygen and nitrogen and add heat?
BOOM.
