When did Silver become an element?
Silver has always been an element. It was first created inside star by fusing together lighter elements using nuclear fusion.
Where are common elements made?
All elements past hydrogen are formed in stars. During the main stage of stars life, it fuses hydrogen into helium. Once it runs out of Helium to fuse, it begins fusing Helium into heavier elements. This continues until iron is formed. Iron gains no energy from fusion, so fusion stops. If the star is massive enough, it will explode in a supernova. The extreme heat can cause the iron to fuse into even heavier elements.
What gives the sun energy?
Nuclear fusion of elements lighter than iron powers all stars. Basically, when two elements fuse together, there is a loss of mass in the "binding" that holds the nuclei together. In accordance with the law of preservation of matter (it cannot be created or destroyed), that must go somewhere. It is essentially "carried away" in the form of energy. It is this energy that is what keeps the sun, and all other stars, going strong. In the sun, hydrogen is fusing to form helium.
What element is made when you fuse 2 carbon molecules?
Actually fusing carbon, such as in a star will create one of several type of elements. In the vast majority of stars carbon is not fused at all, but depending on the star's mass carbon may fuse into neon, oxygen, magnesium, among a couple others. This happens in specific type of stars, at specific times in their lives. Fusing is different from chemical reactions. There are no chemical reactions that can make elements, but with nuclear transmutation you can do it. For example, in a star hydrogen is fused into helium, and sometimes helium into carbon.
What is the combining of atoms called?
It is called Fusing. Or FUSION.
What are the main elements that make up a star?
For main sequence stars, the vast majority is hydrogen and helium. Older stars will exhaust these lighter elements near their cores and begin fusing heavier elements.
What are some characteristics of stars that might account for the fact that some have more complex elements in their spectra?
Older age might account for it. As a star ages, it uses up the simplest elements (hydrogen . . . helium . . .) then starts fusing heavier and heavier elements. Our Sun will get to the point of fusing iron, which is pretty heavy, but the truly large stars out there will fuse elements much heavier than Iron. These heavier and heavier elements may account for some stars having more complex elements in their spectra.
What fuel is used by red giant stars?
After using up its hydrogen-1, the star becomes a red giant. It will start fusing helium-4 into heavier elements. It may also fuse heavier elements, to get other elements that are yet heavier.
Fusing hydrogen atoms into heavier elements produces?
It is believed this was how the universe formed. Hydrogen fuses to form all the other heavier elements on the periodic table up to Element number 92
What is the difference between a red and a blue star?
A red star is fusing mostly hydrogen while a blue star has depleted its hydrogen supply and is fusing helium into heavier elements.
Do all stars turn hydrogen in to helium?
No. Stars that have depleted the hydrogen in their cores may start fusing heavier elements.
Massive stars cannot generate energy through iron fusion because?
No energy is gained when fusing iron into heavier elements. Heavier elements have a higher potential energy (nuclear energy) than iron.
What Fuel does a Star burn to create its own energy?
A star will use fusion to combine lighter atoms into heavier atoms. A main-sequence star (that's the majority of stars) will convert hydrogen-1 into helium-4, so in this case, hydrogen-1 is the fuel. Once it starts running out of hydrogen-1, it will start fusing the helium into heavier elements - in which case the main fuel will be the helium-4. Later in the life cycle of a star, the fuel can be even heavier elements.
What makes oxygen?
Trees and other plants releaseoxygen.Stars make oxygen in their cores by fusing lighter elements together.
Which nuclear fuel is there in the sun?
At this point in time hydrogen is being fused into helium. Many, many years down the line, as the hydrogen runs out, the sun will begin fusing heavier and heavier elements for fuel. At least to iron.
Why aren't there any greenstars?
A star that shined green would be one that was fusing lighter elements into copper. This can happen - for a few seconds prior to the supernova explosion.
When did Silver become an element?
Silver has always been an element. It was first created inside star by fusing together lighter elements using nuclear fusion.
