Depends which atoms you're trying to fuse together.
You need to get the nuclei really close, despite the fact they repel each other. This is more likely at high temperatures and pressures. (the exact detail will vary by element)
Very high pressure and temperature, as at the sun's core
yes
When two atoms need to gain same amount of electrons, they tend to share. That is when bonds are formed. Ex. One atom of oxygen needs two electrons to attain its octet. Another atom of oxygen will also need two electrons. Since both the atoms need electrons they begin to share their electron in the outermost shell. They form double bond since they need two electrons.
It is NOT a chemical reaction, but a FUSION of atoms. Say two atoms of hydrogen may fuse together to form an helium atom , with the consequent release of energy.
"H" is the chemical symbol for Hydrogen. "H2" is the symbol for a molecule that contains two atoms of hydrogen. Under normal conditions in the Earth's atmosphere, hydrogen gas is usually found in the form of molecules consisting of two atoms.
Two or more atoms of different elements can form a bound state where they are bonded one with the other. The resulting complex is called a molecule and has chemical and physical properties completely different from the constituting atoms. An example is water, whose molecule is formed by two hydrogen and one oxygen atoms bonded via the so called covalent bond, that forms when different atoms put an electron in common. Water, liquid at room conditions, has completely different properties from both oxygen and hydrogen, both gasses at room conditions.
Nuclear fusion is caused by a huge amount of energy being absorbed by two atoms that are close to each other and they fuse, or under go fusion to give of that energy. The byproduct of the process is roughly equivalent to the amount of energy that was absorbed by the original two or more atoms.
two hydrogen atoms
yes
two conditions bacteria need to live
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.

You need to include "the above two atoms" for anyone to be able to answer the question.
You need different atoms...?
