Is the ratio of the amount of hydrogen and helium in the sun increasing or decreasing?

Since hydrogen atoms in the sun are fused into helium atoms, the amount of helium is increasing and the amount of hydrogen is decreasing.

Will the amount of hydrogen and helium in the sun increase or decrease over the next few million years?
The amount of hydrogen will decrease and the amount of helium will increase.
Gas giants have atmospheres composed primarily of helium and what?
Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.
What is the compasition of the sun?
Starts with pure hydrogen, fused to helium in increasing proportion as the sun ages.
The sun is composed of what?
mostly hydrogen and helium
What are the Sun's main atmospheric gases?
Hydrogen and helium. Mostly hydrogen.
Why is the amount of hydrogen in the sun decreasing?
The sun is fusing hydrogen atoms together, turning them into helium.
Why does a star's hydrogen supply run out?
The nuclear fusion in a star's core converts hydrogen into helium. Therefore the amount of hydrogen in a star is constantly decreasing.
Will the amount of hydrogen and helium in the sun increase or decrease over the next few million years?
The amount of hydrogen will decrease and the amount of helium will increase.

The amount of hydrogen will decrease and the amount of helium will increase.
Will amount of hydrogen and helium in the sun increase or decrease over the next few million years?
The amount of hydrogen will decrease and the amount of helium will increase.
What is the star Rigel's core made of?
Hydrogen and Helium, with the former decreasing and the latter increasing. Rigel is fusing H into He at a prodigious rate and in a million years or so will start to collapse as its fuel runs out.

Why does the amount of hydrogen in a star decrease?
Because Hydrogen is the fuel of Stars, hydrogen consumed and Helium is formed.
What is the compasition of the sun?
Starts with pure hydrogen, fused to helium in increasing proportion as the sun ages.
When hydrogen changes into helium does it explode as fiery energy?
The fusion of two hydrogen atoms yielding a helium atom expels a large amount energy.
What do the stars in the universe appear to consist of?
Hydrogen and a small amount of Helium.
How does the amount of Hydrogen differ from that of helium in the Sun mass?
The Sun is about 70% hydrogen, 28% helium, and 2% "other". When the Sun gets to about 50% hydrogen, the amount of helium present will seriously interfere with the hydrogen fusion, and the Sun will begin to collapse under its own gravity. The Sun's core is currently around 15 million degrees Kelvin. As the Sun collapses, the increasing pressure will heat the Sun, and when it gets to about 45 million degrees, the Sun will begin fusing helium and with the new power source will expand into a red giant. We expect this to happen in about 4 billion years, perhaps a little more.
