While electrons are transferred from one element to another in ionic bonds, valence electrons are shared in covalent bonds.
The ultimate "goal" of elements in bonding is to complete their outer shell, that is, end up with 8 valence electrons. Elements in ionic bonds accomplish this by giving away or taking electrons until their outer shell is complete; elements in covalent bonds share electrons so that the electrons completing the outer shell of one element are also completing the outer shell of the other.
For example, in the case of O2, both oxygen atoms are looking to complete their outer shells, and both have 6 valence electrons, creating a total of 12 valence electrons. When they bond, they share two pairs of electrons, giving 4 electrons that are shared between the two, and 4 electrons per atom that are not shared. This creates a double bond between the two oxygen atoms (because two pairs of electrons are being shared) and means that while each atom has 8 electrons in its outer shell, because 4 of them are shared, there are still only 12 valence electrons overall.
Thus in covalent bonds electrons are shared between two atoms to complete both outer shells at once.
What else can I help you with?
Coordinate covalent bond formation is a process in which?
Coordinate covalent bond formation is a process in which one atom provides both electrons for the bond, rather than each atom individually contributing one electron. One atom donates a lone pair of electrons to the other atom, resulting in the formation of a shared pair of electrons and the bond.
When two atoms combine by sharing electrons it is a ionic or covalent bond?
When two atoms combine by sharing electrons, it forms a covalent bond. In an ionic bond, one atom transfers electrons to another, leading to the formation of oppositely charged ions that are attracted to each other.
What type of particle results from the formation of the covalent bond?
A shared pair of electrons results from the formation of a covalent bond. These electrons are shared between two atoms to achieve a stable electron configuration.
A bond in which atoms share electrons is called a?
The type of bond in which two atoms share electrons is called a covalent bond.
What results from sharing electrons between nonmetals?
Sharing electrons between nonmetals results in the formation of covalent bonds. In a covalent bond, atoms share electrons to achieve a stable electron configuration. This sharing of electrons creates a strong bond that holds the atoms together.
What is the sharing of electrons occurs in what type of bond?
Sharing of electrons occurs in a covalent bond. In a covalent bond, two atoms share electrons in order to achieve a stable electron configuration. This sharing of electrons results in the formation of a molecule.
What happens to electrons after a covalent bond is formed?
The electrons are shared

A bond in which atoms share electrons is called a?
The type of bond in which two atoms share electrons is called a covalent bond.
Occurs when there is an equal sharing of electrons between atoms?
formation of a covalent bond
What results from sharing electrons between nonmetals?
Sharing electrons between nonmetals results in the formation of covalent bonds. In a covalent bond, atoms share electrons to achieve a stable electron configuration. This sharing of electrons creates a strong bond that holds the atoms together.
What happens to covalent bonds Their electron?
In a covalent bond, electrons are shared between atoms. These electrons are attracted to the positively charged nuclei of both atoms involved in the bond, creating a stable relationship between them. If a covalent bond is broken, the shared electrons are redistributed between the two atoms involved.
Covalent bonds are the formation of two or more chemicals sharing what A protons B neutrons C electrons?
covalent bond is formed by the sharing of electrons
What is a double covalent bond and what happens in it?
A double covalent bond is a type of chemical bond where two pairs of electrons are shared between two atoms, resulting in the formation of a strong bond. This sharing of electrons creates a stable bond and involves the overlap of two atomic orbitals from each atom. Double bonds are commonly found in molecules such as carbon dioxide (CO2) and ethylene (C2H4).
The sharing of electrons in bond formation always involves?
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.
