the elements that form covalent bonds are on the right hand side of the Periodic Table and usually have either 4,5,6,7 electrons in their outer most shell (valence shell). eg carbon, nitrogen, oxygen and flourine. :)
The sharing of electrons in bond formation always involves the outermost electron shell of atoms. This sharing can occur between atoms of the same or different elements in order to achieve a stable electron configuration through the formation of covalent bonds.

In comparison with ionic bonds, the difference in electronegativities of elements in a covalent bond have a lower difference in electronegativities. A covalent bond occurs between two nonmetals that have a difference in electronegativities that is 1.7 or less. Usually an ionic bond has a difference in electronegativities that is greater than 1.7, but not always.
No, in a covalent bond the shared electrons may not always be shared equally between two atoms. Depending on the electronegativity of the atoms involved, one atom may attract the shared electrons more strongly, leading to a polar covalent bond where the electrons are not shared equally.
A covalent bond is formed when electrons are shared between atoms. In a covalent bond, atoms share pairs of electrons in order to fulfill their octet rule and achieve a more stable electron configuration. This type of bond is commonly found in molecules composed of nonmetals.

Elements always want to be stable. That's their main goal. They can become stable by getting (usually) 8 electrons in their outermost energy level. They either gain or lose electrons, depending upon which is easier. This gaining or losing of electrons is called bonding. There are two main types of bonds, covalent and ionic. Covalent is where electrons are shared, Ionic is where electrons are given from one element to another.
covalent bond
A covalent compound is always formed by the sharing of valence electrons(electrons in the last shell).

covalent bonds always share electrons.
Yes, but not always equally. Depends on the elements electronegativity variance. H2O is a polar covalent bond because the oxygen has much stronger electronegativity than the hydrogens, so their are slight charges on the ends of the molecule. NO, nitrous oxide, is just covalent because the elements are of pretty much equal electronegativity.

Carbon has four valence electrons in its outermost orbit which indicate it need four further electrons to complete its valence according to octect rule. It is also not possible for Carbon to remove all of its four valence electrons for the same cause of obeying octect rule. Hence the only option left for carbon is make covalent bonds with another carbon or any other element whose electrons are available for making a covalent bond. That's why most of the compounds of carbon are covalent.
P4O4 is not a chemical compound. P4O10 is a covalent compound. P and O always form covalent bonds.
