What else can I help you with?
Are there other elements found in stars than hydrogen and helium?
Yes. All naturally occurring elements in the universe can be found in most stars, though generally only in small concentrations. Massive stars that have depleted the hydrogen in their cores may start producing elements as heavy as iron.
What is the least massive and the simplest of all elements?
Hydrogen. You could have found this out yourself had you just looked at a periodic table of elements.Not everyone knows what tools to use to find out answers to their questions, using wiki.answers.com is one of the best ways to learn what you want.
Which is the following location in the periodic table would have the least massive atom?
Hydrogen is the least massive element. It is found in group 1, period 1 on the periodic table.
How are different elements produced?
Different elements are produced through various processes in stars and cosmic events. In stars, nuclear fusion occurs, where lighter elements like hydrogen fuse to form heavier elements such as helium, carbon, and oxygen. When massive stars exhaust their fuel, they explode in supernovae, creating and dispersing even heavier elements like gold and uranium through explosive nucleosynthesis. Additionally, elements can form during the Big Bang nucleosynthesis, where the universe's first elements, mainly hydrogen and helium, were created.
What are the stars called brown dwarfs made of?
Brown dwarfs are composed primarily of hydrogen and helium, with small amounts of heavier elements such as oxygen, carbon, and nitrogen. They are not massive enough to sustain nuclear fusion in their cores like regular stars, but they do emit heat and light due to residual energy from their formation.
Is it possible for fusion reaction to be happening at a planets core?
No. Fusion requires high concentrations of Hydrogen. Planets are made from substantially heavier elements. Additionally, a planet massive enough to begin a fusion reaction literally becomes a star.
Is it possible for fusion reaction to be happening at planet's core?
No. Fusion requires high concentrations of Hydrogen. Planets are made from substantially heavier elements. Additionally, a planet massive enough to begin a fusion reaction literally becomes a star.
What causes the sun to burn?
hydrogen is at the heart of a star, meaning that as it reacts it produces a massive amount of heat and light

What elements are in the atomic bomb?
The atomic bomb typically contains enriched uranium or plutonium as the fissionable material, along with conventional explosives to trigger the nuclear chain reaction. When detonated, these elements undergo a rapid chain reaction, releasing a massive amount of energy in the form of heat, blast, and radiation.
What Nuclear reaction that produces energy in stars?
The primary nuclear reaction that produces energy in stars is nuclear fusion, specifically the fusion of hydrogen nuclei (protons) into helium. This process occurs in the core of stars, where extreme temperatures and pressures enable the overcoming of electromagnetic repulsion between positively charged protons. Fusion releases a tremendous amount of energy in the form of light and heat, which counteracts gravitational collapse and maintains the star's stability. In more massive stars, fusion can progress to heavier elements through successive reactions.
Hydrogen bombs and stars both produce energy with nuclear?
fusion reactions, where lighter elements combine to release tremendous amounts of energy. In stars, the fusion of hydrogen into helium powers their luminosity and heat. Hydrogen bombs use isotopes of hydrogen to trigger a controlled fusion reaction, releasing a massive amount of explosive energy.
What type of reaction causes stars to combine hydrogen and release massive amounts of radiation?
This involves "nuclear fusion" reactions.

Are all-stars made of similar elements?
Younger stars often are made up mainly of hydrogen, perhaps with some helium. Less massive stars will only fues hydrogen into helium, so eventually they will end up having a lot of helium. More massive stars however will eventually start fusing helium to metals, i.e., heavier elements. In any case, the "metallicity" (percentage of elements heavier than helium) and the percentages of different elements should vary somewhat between different stars.Younger stars often are made up mainly of hydrogen, perhaps with some helium.

What is the process that produces elements in a stars?
Elements in stars are produced primarily through nuclear fusion processes. In the core of a star, hydrogen atoms fuse to form helium under immense pressure and temperature, releasing energy in the process. As stars evolve, they can fuse heavier elements, creating carbon, oxygen, and even heavier elements in more massive stars. Eventually, during supernova explosions, these elements are dispersed into space, contributing to the formation of new stars and planets.
