Helium is the first fusion product. Sodium even iron can be made. The rest of the elements are made when a star goes super nova. The results is everything that exists.

What is nuclear fission and fusion?
Nuclear fusion is the joining up of two smaller nuclei into one larger, in our sun it is the fusion of hydrogen which produces helium, and releases energy. Nuclear fission is the splitting of the nucleus of uranium which releases energy, as in a nuclear reactor.
The interstellar medium is enriched with heavy elements by the remnants of what?
The interstellar medium is enriched with heavy elements by the remnants of supernovas. A supernova is the spectacular explosion at the end of a stars life when it collapses in on itself.
The amount of energy produced during nuclear fission is related to?
It is related to the specific nuclear reactor design including the nuclear fuel amount and the reactor control system and the energy extracting medium (coolant) capacity.

What is the history of strontium?
Strontium is an element it is made in stars and is blasted into the interstellar medium when stars explode. It can also be made in Human nuclear reactors.
What are the particles for the nuclear fusion in stars?
A variety of different fusion reactions are possible. In our sun, which is classified as medium sized, it is fusion of hydrogen nuclei, ie protons, to form helium. In larger stars, especially red giants, larger nuclei react in fusion, so that larger and heavier nuclei get formed.
What is alkaline medium?
An alkaline medium is formed when alkaline elements in food break down. This happens when they combine with (H+) ions.
Are the fission fragments from a nuclear reactor light, medium, or heavy elements?
They are what could be called medium weight elements. There are two peaks in yield, one around 100 and one around 130 in atomic weights. See the link from Wikipedia below
Does the interstellar medium have many chemical elements not found in stars?
No all Hydogen and most Helium is from the near beginning. All other elements including more He are formed by stellar processes
Does nuclear energy need a medium?
Yes
What elements does the sun ideally burn and produce during nuclear fusion?
Apart from the primordial hydrogen, helium, and a few other light elements that condensed directly from the big bang, virtually all elemental matter in existence today has experienced both nuclear fusion and fission reactions and decay inside stars. Before fission or decay can happen, there first has to be fusion. These nucleons (which can later cool off, gain electrons and become atoms) have undergone many fusion and decay events through a series of stable and unstable isotopes. Fusion happens in two areas - stellar nucleosynthesis and supernova nucleosynthesis.Stellar nucleosynthesis occurs in active stars producing certain isotopes of most of the lighter elements, ranked by atomic number from helium (2) up to zinc (30). When elements up to iron (26) are fused with a helium nucleus (alpha particle), they release energy, and this energy helps the star continue with more fusion reactions. The isotopes of cobalt (27), nickel (28), copper (29), and zinc (30) produced by fusion are not stable and decay back into lighter elements. Iron-56 (atomic number 26) is the heaviest stable isotope produced by Stellar nucleosynthesis. Up to this point, fusion reactions are exothermic, meaning they produce excess energy. Fusion reactions that result in elements heavier than iron start to become endothermic, meaning they absorb heat from the environment.Heavier stable elements cannot be produced by a stellar nucleosynthesis. The fusion reactions producing them are endothermic - they don't return as much energy as they absorbed from the environment to activate. When massive stars run out of fuel for exothermic reactions and try to burn too many heavy elements, the net energy production falls off, the temperature and pressure that normally push the particles apart diminishes, volume decreases, and the star begins to collapse under its own weight. The crowding of nucleons happens as the strong nuclear force is overcome. The mass of the star will then determine if it explodes and/or forms a dwarf, neutron star, or black hole. If it explodes in a supernova, the energy released will support the endothermic fusion reactions needed to form isotopes heavier than iron during supernova nucleosynthesis. These fusion reactions are also known as neutron capture or proton capture. Supernovae return all these formed elements to the interstellar medium, clouds of "stardust" from which solar systems like ours then formed.Controlled fusion is theoretically possible for humans to conduct on Earth. Tritium and Deuterium, both isotopes and components of 'heavy water', would be fused in a tokomak reactor to create Helium, surplus neutrons and gamma radiation (heat).
Is a brown dwarf star on its way to becoming a black dwarf?
No. A brown dwarf is a star that has too low a mass to start nuclear fusion. A black dwarf is a former white dwarf, the remnant of a low to medium mass star that ran out of fuel in its core.

What is the six factor?
The six-factor formula is used in nuclear engineering to determine the multiplication of a nuclear chain reaction in a non-infinite medium.
Describe the sun as a star?
A star is a luminous, approximately spherical plasma that converts mass into energy by nuclear fusion reactions in its core. Stars mainly convert hydrogen into helium during the longest stage of their evolution known as the main sequence. Stars are formed from clouds in the interstellar medium known as nebulae. Their fate depends primarily on their mass. They may end up as white dwarfs, neutron stars, or black holes. Stars that are very massive explode as supernovae. The Sun, which is at the center of our solar system, is an example of a star.
What two types of nuclear weapons were found in cuba?
