Covalent bond :)
The four most common halogens: fluorine, chlorine, bromine, and iodine, exist in nature as a covalently bonded diatomic molecule. They each have seven valence electrons, so by sharing one pair of electrons, they can both satisfy the "octet rule" and have eight valence electrons, which is what they want. So the bond is covalent, since they share.
Non-metal atoms form covalent bonds in which their unpaired valence electrons are shared between the atoms. This sharing has the overall effect of giving both atoms an octet of valence electrons, or two valence electrons in the case of hydrogen.
An ionic bond is formed.
That would be a description of water, i.e. H2O
A nonpolar covalent bond involves an even sharing of electrons.
While forming a covalent bond, valence electrons are shared.

If I understand the theory correctly, then it is safe to assume that any molecular bond is based on the valence system. Valence bonding occurs when orbitals of electrons are slightly overlapped. Your question should rather be 'what kind of valence bond occured in the bond. There are 2 types namely sigma and pi. Sigma bonds occur when the orbitals of two shared electrons overlap head-to-head. Pi bonds occur when two orbitals overlap when they are parallel (wikipedia). So it is safe to assume that any bond that is covalent can be described using valence theory.
Valence electrons are the electrons in the outer energy level. Each period shares many similar characteristics, one of which being the amount of electrons in the outer energy level. If you are unfamiliar, the Periods are the Vertical Columns, and Families are the Rows. I hope this helps you.
An atom in a compound sharing electrons with another atom or atoms is participating in a bond or could be said to be bonded, or bound. In somewhat simplistic terms it would be considered a covalent bond; in reality, bonds of this kind are on a continuous scale with an ionic-like bond at one end and a covalent at the other, wherein the more it shares electrons the more it is characterized as covalent.

When a bond is formed by atoms by sharing the electrons, the bond is called a covalent bond.
