The star can fuse up to iron, because iron is the most stable element.
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.
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.
Hydrogen is the least massive element. It is found in group 1, period 1 on the periodic table.
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.
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.
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.

hydrogen is at the heart of a star, meaning that as it reacts it produces a massive amount of heat and light

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.
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.
This involves "nuclear fusion" reactions.

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.

No, the sun does not reproduce. It is a massive, constant nuclear fusion reaction that creates energy through the conversion of hydrogen into helium in its core.
Stars are made mostly from hydrogen. The more hydrogen available when a star is formed, the more massive it will be.
