Essentially yes; the sun's energy comes from nuclear fusion with hydrogen being converted to helium.
The element that creates the energy that causes the sun to shine is hydrogen. Through a process called nuclear fusion, hydrogen atoms in the sun's core combine to form helium, releasing vast amounts of energy in the form of light and heat.
Enough, it has been hypothesized, to maintain it in its present stable state for another 4.5 billion years from now, before it begins to readjust itself to its dwindling supply of fuel for fusion.
The distinguishing feature is that a brown dwarf gets hot enough to fuse deuterium (hydrogen-2), but not hot enough to fuse hydrogen-1.
hydrogen
The hydrogen in the Sun is fuel for the nuclear fusion reaction.
Hydrogen
The sun is mostly made up of hydrogen, undergoing nuclear fusion to produce energy. It is estimated that the sun has used about half of its hydrogen fuel in its core, and it has enough fuel left to continue shining for about another 5 billion years.
Our sun, Sol, uses hydrogen for fuel.
no hydrogen is not affected by the sun because hydrogen can be combined with helium it creates a fuel source but it is not affected by hydrogen by it self so no hydrogen is not affected by the sun
Hydrogen is the fuel used by the sun, helium is the waste produced by hydrogen use in the fusion process
It's hydrogen, which is MADE INTO helium with a release of energy. As the Sun gets older, it will use up most of its hydrogen and start to use helium fuel to make carbon, but the process won't be as efficient and will be over sooner. The Sun isn't big enough to make heavier elements, but each stage is quicker and less effective than the last. Very big stars will at last start to make iron, but that's the end, because iron cannot be made into other elements unless it's GIVEN more energy. We get energy out of light atoms when they COMBINE, and energy from heavy ones when they BREAK APART. The Sun has enough hydrogen to put off the helium-combining stage for 5 billion years or so.
No, it is hydrogen that is the fuel for fusion in the sun
The nuclear fuel of the sun is hydrogen. The Sun binds the hydrogen atoms into helium, which creates energy in the process.
pure hydrogen
If source you mean, fuel...then the answer is Hydrogen gas. The sun fuses to hydrogen atoms to create helium.
There's hydrogen at the core of the sun - that's the sun's main fuel - but earth's core is mostly iron and nickel.
