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. :)

What is type of covalent bond in which one an atom donates both electrons?
single
Which kind of bond is formed when electrons are shared between atoms?
A covalent bond occurs when atoms share electrons.
The sharing of electrons in bond formation always involves?
Shared electrons produce a covalent bond.
Why do carbon always forms covalent bond?
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.
What happens with the electrons when a covalent bond forms?
The electrons are shared between the two atoms that bonded, combining the total number of electrons in a large electron cloud. In a polar covalent bond, one atom shares, or "attracts" most of the atoms, while in a nonpolar covalent, they are equally shared. Covalent atoms are always only shared, unlike with ionic compounds, which "steal" electrons from the other atom.
What cause a bond to form?
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.
A chemical bond that forms when atoms share electrons is always an?
covalent bond

Most often a covalent bond is formed by?
A covalent compound is always formed by the sharing of valence electrons(electrons in the last shell).
A chemical bond that forms when atoms share electrons is an?
covalent bonds always share electrons.
Are Electrons are shared in a covalent bond?
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.

How many electrons are in the highest occupied energy level atom barium?
2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons
Unequal sharing of electrons between two bonded atoms always indicates?
a polar covalent bond
