So they can have a full outer shell.
Bonds are formed between two atoms because that results in a more stable state for the atoms. This is a result of electron configuration where most atoms want to have 8 electrons in their outer-most orbital (there are exceptions to this rule, however).
The electrons in atoms are the important particles in covalent bonds. The electrons in an atom are negatively charged, and when two atoms share electrons, this allows their electric field to become more stable.
Atoms form bonds with other atoms in order to achieve a more stable arrangement of electrons in their outer energy levels. By sharing or transferring these electrons, atoms can achieve a full outer electron shell, which is a more energetically favorable state. Bond formation allows atoms to increase their stability and decrease their overall energy.

It depends on the properties of the atoms. But, basically they join together to satisfy the octet rule. Octet rule stated that every atom will want to have eight valence electrons. So when atoms join? Answer: when they found a pair that can satisfy that rule (either covalent or ionic.) Also, it depends on the temperature and pressure.
look at the numbermber of valance electrons in a given element then see if you could get it to combine with carbons valence electrons to add up to 8 theres too many compounds to count remember you can have as many atoms in a molicule as you want and carbon combines with itself to equil 8 electrons it has four valence electrons
Electronegativity describes "how much" an atom "wants" an electron. Some with high electronegativities will be able to "steal" electrons from other atoms and form ionic bonds. If two atoms have comparable electronegativities, then electrons will be "shared" and a covalent bond will form.
as many as u want :P
Chemists are interested in the structure of materials and how they interact with each other. This necessitates that they understand compounds which are made up of atoms. Atoms combine together by means of their electrons.
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.
No, atoms with filled valence shells do not tend to form chemical bonds because a filled valence shell means the atom is already stable. It doesn't "want" to share with or take electrons from other atoms to become stable. Although sometimes, these atoms can be found in compounds, it takes a great deal of energy and forcing.
Neon is an inert or noble gas. It does not want to bond with other atoms because its valence shell is complete. It will not even hang out with its own kind; it's a monatomic gas. Having said that, perhaps it becomes obvious that neon doesn't form any kind of bond as we normally encounter it.
