A chemical bound is created when two or more atoms bonds together to form a molecule. This bond does not involve atomic nuclei and it is mainly generated by the interaction between the external atoms electrons.
If the bond is created by sharing electrons, that is by modifying electrons orbitals from a situation where the orbital completely belonging to a certain atom to the situation in which it is shared among two or more atoms, the bond is called covalent. n astounding example is the benzene ring bond, where electrons are shared among all six carbon atoms of the molecule. Covalent bonds are generally the strongest among chemical bonds.
When two charges atoms (that is two ions) are bonded by the reciprocal electromagnetic attraction we have a ionic bond, that is also a strong bond. The table salt crystal for example (NaCl crystal) is created by ionic bonds between the ions Na+ and Cl-.
Another very interesting type of strong bond is the metallic bond created when external electrons are put in common by a huge number of atoms (nominally all the atoms forming a macroscopic piece of crystal). This kind of "almost free" electrons generate the good electrical and thermal conductivity of metals and metals optical properties (like the shining surface foor example). All metal crystals like iron, copper, gold and so on, are created byy this kind of bond.
More complex bonds, as polar bonds or hydrogen bonds or van der Waals bonds, can be craeted among molecules, but signle atoms are not so complex to give rise to this complex structures.
In order to fill their valence shell and become more stable.
This question is potentially very deep if you want to get into quantum physics and the general direction of our universe and things like that.
At least two (or even more) atoms should combine to form a molecule. The bond between the molecules can be ionic or covalent or coordinate covalent.

Yes. Chemical bonds include covalent bonds and ionic bonds.
yes
nonpolar
Actinides are metals, they form metallic bonds with same atoms and ionic bonds with non metals.
Hydrogen bonds are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds within and around large molecules.
People can use electronegativity and energy to discuss theories of how and why atoms form bonds. Atoms will only form bonds if it is a lower energy state for them to be in. Bonds are formed by electron sharing.
Covalent bonds are formed when atoms share electrons
The types of bonds are corporate bonds, junk bonds ,treasury bonds and municipal bonds. There are saving bonds also.
Carbon will almost always form bonds with other carbon atoms, and that is part of what makes it such a useful element.
