When does a covalent bond form?
A polar covalent bond is formed when 2 atoms are sharing the same electron unequally. It occurs because one of the atoms has a stronger affinity for electrons that the other.
What bond shares electrons unequally?
Polar Bond: A type of covalent bond between two atoms in which electrons are shared unequally. Because of this, one end of the molecule has a slightly negative charge and the other a slightly positive charge. Credit to: Wikipedia Resource
When a pair of electrons is shared unequally between two atoms the bond formed is?
Such a bond is said to be polar. A polar bond is formed when electrons are unequally shared between two atoms. Polar covalent bonding occurs because one atom has a stronger affinity (preference) for electrons than the other (yet not enough to pull the electrons away completely and form an ion).
What is an covalent bond where the electrons are unequally pulled towards a certain ion is called?
I think you are referring to a "dipole". In most covalent bonds, the electrons that form the bond are not equally shared by the two atoms involved, but are -- as you say -- preferentially pulled towards one atom or the other. This results in a slightly higher electron density around one atom and slightly lower electron density around the other called a dipole. But note: atoms in covalent bonds are not called "ions". They are still referred to as atoms.
Covalent bonding of one atom to another is the result of?
It is formed by a pair of electrons shared between 2 atoms. the nucleus of the atoms attract each other, and 2 atoms share a pair of electrons. This is a single covalent bond. In a double covalent bond, 2 pairs of electrons are shared between 2 atoms. 3 pairs are shared in triple bonds.

Covalent bonds are formed when electrons are what?
Electrons are shared. they may be shared equally if the elements are nearly equal in electronegativity; a nonpolar covalent bond. Or they may be shared unequally, that is the electrons may spend more time in one atoms orbital than the other atoms orbital(s), if the electronegativity variance is great; a polar covalent bond.

In a molecule with covalent bonding?
In a covalent bond, a pair of electrons is shared equally between two atoms. In an ionic bond, one atom gives its electron to the other atom, causing one of the two atoms to become positively charged and the other to become negatively charged. These two atoms are then attracted to each other because of their opposite charges. In most bonds, the electrons are somewhere between purely covalent and purely ionic, so that the electrons are not completely transferred, but they are shared unequally between the two atoms. The degree to which the electron is unequally shared or transferred is based on the difference in electronegativity for the two atoms. The greater the electronegativity difference, the more unequally an electron is shared. If the electronegativity difference is greater than 2.7, it is considered to be an ionic bond. However, covalent bonds that have an electronegativity difference of greater than 0.4 are considered polar covalent, that is, covalent bonds with a slightly ionic character.
What bond occurs between atoms that do not share electrons equally?
Atoms that do not easily lose electrons form covalent bonds with other atoms. That is, they share electrons.

How can atoms combine with other atoms?
By sharing electrons in covalent bonds or by transferring electrons in ionic bonds
What do atoms gain or lose when they bond?
If the chemical bond is ionic, an electron is gained or lost. If it is covalent, the electron is shared equally; if it is polar covalent, the electron is shared unequally. If the bond is intermolecular, no parts of the atom are actually shared, gained, or lost; the atom itself is simply attracted to other atoms.
How many electrons must the atoms of S share with other atoms in covalent bonding to achieve an octet of electrons?
two electrons

What is a carbon covalent bond?
Carbon forms covalent bond when it shared electrons with other atoms.
