The Sun is, at present, about 90.1% hydrogen and 9.9% helium and a small mixture of heavy elements(iron, calcium,sodium).This changes slowly over time as the Sun converts hydrogen to helium in its core.
The sun is mainly hydrogen gas (91.2% )which burns to form helium (8.7%). Traces of other heavier elements are formed by fusion reactions such as oxygen, carbon, nitrogen, silicon, magnesium, neon, iron and sulfur (all of these are much less than 1% of the total mass of the Sun.
Hydrogen-1 is converted into helium-4, at a high temperature and pressure, in a process known as "nuclear fusion". This produces a lot of energy. For details about the main reaction occurring in the Sun, take a look at the Wikipedia article on the "proton-proton reaction".
Not solely. The surface of the Sun consists of hydrogen (74%), helium (24%), and trace quantities of other elements, including iron, nickel, oxygen, silicon, sulphur, magnesium, carbon, neon, calcium, and chromium. The hydrogen turns - by nuclear fusion - to helium and when the hyrdrogen fusion process ends the helium will in turn fuse into other elements.
Technically, it is made up of plasma - i.e., ionized gas. This is considered another state of matter.
The most common element in the Universe - at its current stage! - is hydrogen, followed by helium. At some point, such gases (and a smaller amount of heavier elements) come together to form a star (such as the Sun). Due to the extreme heat generated when a star is formed, which is later increased by the nuclear fusion in the star's core, ANY material within the star can only be in the form of a gas - or rather, a plasma.
Closer to 30% actually, but the helium is the "ash" left over from the nuclear fusion "fire" that powers the Sun.
We believe that our Sun was mostly hydrogen when the solar system formed, and when the gravity of all that hydrogen pulled it all together, it compressed and heated the hydrogen gas. At about 15 million degrees, nuclear fusion started to generate energy, keeping the Sun shining. Four atoms of hydrogen come together to form one atom of helium, and leaves a little energy left over.
5 billion years or so from now, the helium will be over 50% of the Sun's mass, and it will start to collapse again. This increases the pressure and the temperature, and at about 30 million degrees, the helium itself will begin to fuse, causing the Sun to expand into a red giant. After another billion years, the Sun will begin to collapse into a white dwarf, and begin to die out.
The Sun is about 70% hydrogen, 28% helium, and about 2% heavier elements. As time goes on, the Sun's nuclear reaction is fusing hydrogen into helium, so that the proportion of hydrogen is slowly falling and the percentage of helium is slowly increasing.
Yes, but it doesn't actually "burn" it, it goes through nuclear fusion, fusing into helium.
the sun is primarly made of plasma and constent fusion.
The sun is composed of about 73% Hydrogen, 25% Helium, and 2% Oxygen... This means that the sun is mainly composed of Hydrogen
No. helium does not react with any other element
why helium does not react with other elements to form compounds
The sun in composed of 25 percent helium. The other 75 percent is hydrogen. The sun also has small amounts of other elements such as neon, oxygen, carbon, and magnesium.
No. helium does not react with any other element
Saturn is approximately 75% hydrogen and 25% helium with traces of other substances like methane and water ice.The composition of Saturn's atmosphere is that it contains mainly hydrogen and some helium.
They are composed of mainly hydrogen and helium.
All stars are mainly composed of hydrogen. Stars also contain small amounts of helium and trace amounts of other elements such as nitrogen, oxygen, and carbon.
Oxygen is an element as are Hydrogen and Helium. It is not composed of other elements. Minerals are combinations of elements.
Helium is one element and does not chemically react.
hydrogen,All stars are composed primarily of hydrogen. Stars can also contain some other elements such as helium, but hydrogen accounts for the majority of a star's composition.
No. helium is chemically inert and does not combine with other elements.
A star like our sun is composed of 73% hydrogen, 25% helium, and 2% other elements
NO!!!! He (Helium) is monatomic gas, that is it exists as single atoms, and does NOT combine with any other substance to form a compound. 'He' is the most inert element of all. It alsao has the lowest condensing point 4K4 (-269 oC) and freezing point at 2K (-271oC).
No. helium does not react with any other element
Helium is itself a chemical element and therefore is not found in any other chemical element.
Helium is chemically inert; it does not combine with any other element.
