The other elements that the sun is comprised of are oxygen, iron, silicon, nickel, sulfur, magnesium, neon, carbon, chromium and calcium. Oxygen is 1 percent of the total mass of the sun, while the other elements constitute 1 percent of the total composition of the sun.

Sun It is also in the core where the majority of the Sun’s energy is produced through nuclear fusion, which converts hydrogen into helium. Nearly 99% of the thermal energy created by the Sun occurs within this region – which accounts for 24% of the Sun’s interior. By 30% of the radius, fusion processes have nearly ceased.he Sun is presently in it’s main sequence phase, which is characterized by the ongoing production of thermal energy through nuclear fusion. Currently, more than four million tonnes of matter is converted into energy within the core, producing neutrinos and solar radiation.

It's Elemental Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. It is estimated that 90% of the visible universe is composed of hydrogen. Hydrogen is the raw fuel that most stars 'burn' to produce energy. The same process, known as fusion, is being studied as a possible power source for use on earth. The sun's supply of hydrogen is expected to last another 5 billion years. Hydrogen is a commercially important element. Large amounts of hydrogen are combined with nitrogen from the air to produce ammonia (NH3) through a process called the Haber process. Hydrogen is also added to fats and oils, such as peanut oil, through a process called hydrogenation.

What is the Sun made of? Hydrogen is the predominant element of the Sun, accounting for some 74% of its mass, and 92% of its volume. Helium accounts for 24% of its mass but only 7% of its volume. Traces of oxygen, iron, silicon, sulphur, carbon, neon, nickel, magnesium, calcium and chromium make up the missing percentage.The most abundant metals are oxygen (roughly 1% of the Sun's mass), carbon (0.3%), neon (0.2%), and iron (0.2%).he Sun is made of plasma, almost entirely hydrogen and helium. Plasma is superheated matter that is so hot that the elements have lost some or all of their electrons, it is beyond a gaseous state.

Abundance of the chemical elements As another example, looking at the mass-fraction abundance of hydrogen and helium in both the Universe as a whole and in the atmospheres of gas-giant planets such as Jupiter, it is 74% for hydrogen and 23-25% for helium; while the (atomic) mole-fraction for hydrogen is 92%, and for helium is 8%, in these environments.

The core extends from the sun's center to about a quarter of the way to its surface. Although it only makes up roughly 2 percent of the sun's volume, it is almost 15 times the density of leadand holds nearly half of the sun's mass.

Space Environment http://antwrp.gsfc.nasa.gov/apod/ap990113.html. Scientists think that the core of the Sun is a 15 million degree Celsius plasma, a soup of electrons and protons that are stripped from hydrogen atoms. This soup, called plasma, makes up 90 percent of the Sun.

It's Elemental Hydrogen was first recognized as a distinct element by Henry Cavendish in 1766. Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. It is estimated that 90% of the visible universe is composed of hydrogen. Hydrogen is the raw fuel that most stars 'burn' to produce energy. The same process, known as fusion, is being studied as a possible power source for use on earth.

Sun The Sun’s extends from the center to about 0.25 of the solar radius. It has a density of 150 g/cm 3 and a temperature of close to 13,600,000 K. Energy is produced by nuclear fusion during a series of steps called the proton-proton(P-P) chain, converting hydrogen to helium.

The composition of the human body is seen to be distinctly different from the abundance of the elements in the Earth's crust.The elements upon which life is based are often summarized by the combination CHONPS, carbon, hydrogen, oxygen, nitrogen, phosphorous and sulfur.ll others. 1.5. Given the abundance of oxygen and silicon in the crust, it should not be surprising that the most abundant minerals in the earth's crust are the silicates. Although the Earth's material must have had the same composition as the Sun originally, the present composition of the Sun is quite different.

Nuclear Fusion in the Sun Low mass stars, such as our Sun, use the proton-proton reaction to generate almost all of their energy. More massive stars can use more efficient reactions (which you learn about in the next unit). Regardless of reaction used, however, the net result is always the conversion of 4 hydrogen atoms into a helium atom. This turns out to be the most basic defining process for stars. Where have all the neutrinos gone?

- The growing core burns the Sun's hydrogen yet more rapidly, which in turn only enlarges the core more rapidly. . . . In short, in the end, the nuclear furnace at the center of every star begins to overheat. To put numbers on this, when the Sun was formed 4.5 billion years ago it was about 30% dimmer than at present.

- The sun is a big ball of gas and plasma. Most of the gas — 91 percent — is hydrogen. It is converted into energy in the sun's core. The energy moves outward through the interior layers, into the sun's atmosphere, and is released into the solar system as heat and light.

Hydrogen If these protons are called hydrogen, then hydrogen is by far the most abundant element in the Sun, with helium second and everything else much rarer. The Sun's energy is produced by fusion of protons to form helium (alpha particles), in the proton-proton chain.

What Is the Sun Made Of? The temperature of the sun in this layer is about 27 million degrees Fahrenheit (15 million degrees Celsius). Hydrogen atoms are compressed and fuse together, creating helium. This process is called nuclear fusion. As the gases heat up, atoms break apart into charged particles, turning the gas into plasma.

Star When stars form in the present Milky Way galaxy they are composed of about 71% hydrogen and 27% helium, as measured by mass, with a small fraction of heavier elements. Typically the portion of heavy elements is measured in terms of the iron content of the stellar atmosphere, as iron is a common element and its absorption lines are relatively easy to measure.

What kind of material is the sun made out of? Confidence votes 17. The Sun is a star, just like any of the other stars you see in the night sky, only it is much closer to us than any other, which is why it provides us with light and heat. Like all stars, the vast majority of the sun's material is Hydrogen gas.Hydrogen is the smallest and lightest of all the elements, just 1 proton and 1 electron. The mass of a star is enormous (our sun is a 'typical' average sized star and it is hundreds of thousands of times more massive than the Earth.ue to its enormous gravity, the hydrogen atoms in the center of the sun are crushed together so tightly that they literally fuse together (the process is called fusion). It is a nuclear reaction which releases a large amount of energy.
