Are newly discovered elements products of combustion?
Newly discovered elements, those odd trans-uranium metals that inhabit the extreme upper end of the periodic table, are notproducts of combustion. Combustion is, in general, a chemical process. Only a nuclear process of some kind can create these ultra-heavy elements. We know that the elements up through uranium are created in stars (with the trans-iron elements created in supernovae). The heaviest elements, those that are most recelty discovered, were created by man.We use some kind of nuclear accelerator (like a cyclotron, for example) to launch particles or heavy nuclei at samples of the heaviest elements. This can result in having those target nuclei capture the particles or heavy ions and change into a yet heavier element. Additionally, continuous bombardment produces heavier still nuclei (along with a good bit of radiation).
What atoms make up uranium?
Uranium is a very heavy (dense) metal said to have formed in supernovae about 6.6 billion years ago.It is a radioactive element found in many rocks in the Earth's crust.
Does all of the element on the prodic table find naturally on earth?
No, any elements heavier than uranium were created by man and are not found anywhere on earth or possibly anywhere in the universe except on another planet with intelligent beings that are capable of creating new elements.
Where do all of the elements that are heavier than hydrogen come from?
Forming elements heavier than iron and nickel requires the input of energy. Super nova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The star then collapses and explodes. Nuclei with mass heavier than nickel (gold, silver, lead, uranium, etc.) form in the explosions. This is called nucleosynthesis. These elements form over seconds, compared to the lighter ones that took billions of years to form, and are much rarer. This material is thrown out into space and can end up in later generation stars and planets.
What elements are likely be formed by the sun at some time in its life a helium and carbon b iron and uranium c hydrogen and iron d carbon and lead?
A. Helium and carbon. The other heavier elements such as iron, uranium and lead will be created only in the explosions of supernova stars, such as the one discovered just last week (late May, 2011).
What makes uranium lighter than other elements?
Uranium is not lighter but heavier than many of the other elements; the density of uranium is 19,05 g/cm3 and the atomic weight is 238,02891.
What kind of scientists produce elements heavier than uranium?
Physicists and chemists

What atoms are heavier than iron?
There are many elements that are heavier than iron, including lead, gold, platinum, osmium, uranium, etc. Look at the periodic table of the elements.
Scientists make elements heavier then uranium in machines called?
Particle accelerators and nuclear reactors
How many elements have been created or discovered by scientist?
All the elements after Uranium (U).
Is lead heavier than uranium?
Yes, uranium is more dense (heavier) than lead.
What atoms make up uranium?
Uranium is a very heavy (dense) metal said to have formed in supernovae about 6.6 billion years ago.It is a radioactive element found in many rocks in the Earth's crust.
Where are elements larger than uranium created?
There are some elements that are larger than Uranium in atomic size that occur naturally, however these are few and far between, and are usually very rare elements. Some synthetic elements can be created using an Atomic Collider, but when this happens, the atoms, which are almost certainly very radioactive and very unstable, will expire before proper studies can be made, due to a half life of >1 second.
Does all of the element on the prodic table find naturally on earth?
No, any elements heavier than uranium were created by man and are not found anywhere on earth or possibly anywhere in the universe except on another planet with intelligent beings that are capable of creating new elements.

Does uranium come from a living organism?
No, but a living organism can get uranium poisoning. Scientists say that all the Earths uranium came from 1 or more supernovae about 6 billion years ago.
