Which is the first step in the p-p chain of nuclear fusion?
The first step in the proton-proton chain of nuclear fusion is when two protons fuse to form deuterium, releasing a positron and a neutrino in the process.
What does hydrogen nuclei combine to form a nucleus?
Hydrogen nuclei, which consist of single protons, can combine through nuclear fusion to form helium nuclei under extreme temperatures and pressures, such as those found in the cores of stars. During this process, two hydrogen nuclei (protons) can fuse to create deuterium (a hydrogen isotope), releasing positrons and neutrinos. Additional reactions can then convert deuterium and protons into helium-3 and ultimately helium-4. This fusion process releases a significant amount of energy, which powers stars and produces light.
What is the resulting nucleus if a tritium and a deuterium nucleus fuse?
Helium and a neutron: D + T --> He + n + 17.59 MeV
How does hydrogen turn into helium in nuclear fusion?
The simplest and easiest reaction to do is deuterium tritium fusion, this makes helium-4 and a free neutron.The next simplest is deuterium deuterium fusion, this can make any of 3 products: helium-4, helium-3 and a free neutron, or tritium and hydrogen.The hardest is multistep, hydrogen hydrogen fusion, this makes helium-2 which instantly beta decays to deuterium, followed by deuterium deuterium or deuterium tritium fusion.There are various other pathways too.
What is the most common typle of nuclear fusion in the sun?
The most common fusion in the sun is two hydrogen atoms fusing to produce helium. There are different ways this can happen. Two deuterium atoms may fuse, or a deuterium atom may fuse with a tritium atom, or two tritium atoms may fuse. Since the half life of tritium is rather short, the overwhelming majority of these atoms are deuterium atoms. The commonest form of hydrogen, known as protium, does not take part in the process.
When is energy in the sun produced?
..particles (nuclei) fuse together to form heavier nuclei. Initially, two protons fuse together (hydrogen atom nuclei) to form deuterium. These in turn may fuse with further protons, or with another deuterium nuclei to for a helium nuclei. As the heavier nuclei form, lots of energy is released.
What are elements the sun uses to produce energy?
Its mainly going to be Hydrogen nuclii. At the suns core, two protons fuse together (hydrogen atom nuclei) to form deuterium. These in turn may fuse with further protons, or with another deuterium nuclei to for a helium nuclei. As the heavier nuclei form, energy is released. Later on in the Stars life, fusion of the helium nuclii may take place a lot more often, as the preferred fuel of Hydrogen is depleted.
What occurs in a core of a star as the protons collide?
The atoms in the core of a star fuse together under the intense pressure, producing vast amounts of heat and energy.

What converts hydrogen to helium in the sun?
The basic reactions: First 2 hydrogen nuclei (protons) fuse to form deuterium, a hydrogen isotope (1 proton, 1 neutron). Deuterium then fuses with another proton to form a light helium isotope, helium3 (2 protons, 1 neutron. 2 helium3 nuclei fuse to form Helium4 (2 protons 2 neutrons), + 2 hydrogen nuclei (protons).

What prevents two protons from combining?
the electromagnetic repulsion. they are both positively charged particles, and just like putting the south ends of a magnet together, they are actually repelled. what stops them from flying apart is the strong nuclear force. gravity is also an attractive force between them yet it is so weak that it is negligible when being compared to the electromagnetic repulsion.
