What else can I help you with?
Are helium and iron compounds?
No. Both are elements. Helium is a noble gas and iron is a transition metal.
What is the best title for helium iron and oxygen?
THe elements
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 is the role of hydrogen and helium in the sythesis of elements?
Hydrogen and helium are the most abundant elements in the universe. And stars use them for power. To put it simply, hydrogen is fused into helium, and helium into carbon. All the heavier elements are made from there up through iron. The trans-iron elements are made is a supernova. It could be argued that hydrogen and helium are the basic building blocks of other elements.
Which five elements have been discovered between hydrogen and iron?
The elements discovered between hydrogen and iron are helium, lithium, beryllium, boron, and carbon.
Are helium and iron compounds?
No. Both are elements. Helium is a noble gas and iron is a transition metal.
What do astronomers consider heavy elements?
Astronomers consider elements beyond hydrogen and helium, such as carbon, oxygen, nitrogen, and iron, as heavy elements. These elements are created through processes like nuclear fusion in stars and supernova explosions.
Is iron denser than helium?
Yes, iron is denser than helium. Iron is a metal with a high density, while helium is a light gas that is less dense than most other elements.
What is the best title for helium iron and oxygen?
THe elements
Where did all the elements come from?
Hydrogen, some helium and less lithium are the result of the big bang. All the other elements are made inside the cores of stars, except for elements heavier than iron. All elements heavier than iron are created during supernova explosions.

What is first elementslight elements and heavy elements?
The light elements in the universe, such as hydrogen and helium, were created during the Big Bang. Heavy elements, like carbon, oxygen, and iron, were formed in the cores of stars through nuclear fusion processes.
Which five elements have been discovered between hydrogen and iron?
The elements discovered between hydrogen and iron are helium, lithium, beryllium, boron, and carbon.
What is in a supernova?
there is Hydrogen, Iron, Helium, Uranium and most of the elements. up to the 26th element
How do stars other elements?
for making elements from helium to nickel and iron, thermonuclear fusionfor making elements past nickel and iron a supernova explosion is needed to force nuclei to fuse more, this destroys the star
What is events of occurring in the sun?
Nuclear fusion: mainly of hydrogen into helium. To a lesser extent there is fusion of helium into larger elements - all the way to iron.
