Basically because both nuclei are positively charged so repel each other.
Nuclear fusion occurs when two nuclei fuse together. This is frequently nuclei of deuterium and tritium (both hydrogen isotopes), which form a helium nucleus plus a neutron.
Nuclei can fuse together through a process called nuclear fusion, which involves the combination of two light nuclei to form a heavier nucleus. This process releases a large amount of energy and is the source of power in stars, including the Sun. Nuclear fusion requires extremely high temperatures and pressures to overcome the electrostatic repulsion between positively charged nuclei.
No, an element depends on the average amount of electrons it has. Actually in stellar nuclear fusion it takes 4 hydrogen nuclei to fuse to make one helium nucleus, the process is called proton-proton burning.
The positive charges of hydrogen nuclei cause repulsion, it is very difficult to bring two hydrogen nuclei close enough for them to fuse into helium. However, if they can be forced to fuse, a huge amount of energy is released.
..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.
Hydrogen nuclei (protons) fuse together and produce helium nuclei
Basically because both nuclei are positively charged so repel each other.
Fusion is only possible with small nuclei because larger nuclei have stronger repulsive forces between their positively charged protons, making it harder for them to come together and fuse. Small nuclei have weaker repulsive forces, allowing them to overcome this barrier and fuse together to release energy.
The nuclei of the egg and sperm cells fuse to form the fertilized egg.
When hydrogen nuclei fuse together, they can form helium. This fusion process is the energy source for stars, including our sun, where hydrogen nuclei combine to form helium through a series of nuclear reactions.
nuclear fission
Three helium nuclei, also known as alpha particles, fuse together to form a carbon atom in the process of stellar nucleosynthesis.

The 'ionic' nuclei of Hydrogen atoms (protons).
Nuclei can fuse together through a process called nuclear fusion, which involves the combination of two light nuclei to form a heavier nucleus. This process releases a large amount of energy and is the source of power in stars, including the Sun.
