How do covalent bonds work?

Answer 1

Covalent bonds form when two nonmetals share an electron.

Hi Covalent bonds occur when nonmetal elements have a unstable outermost shell know as the valence electrons. The two non-metal either give up of gain electrons and then live with the other element or elements outer shell. A common everday example is water also know as H20 it has 2 hydrogens and one oxygen. Oxygen's has 6 valence electrons so it need to electron to have a full outermost shell. Hydrogen has one 1 electron in its valence shell, so one 1 electron joins the 6 electron, but oxygen needs 8 for a full outer shell so another hydrogen joins in and then all three have full outer shells because they all live in the valence shell. Hydrogen joins oxygen because it wants to get rid of its valence cell, so another joins in so oxygen can get a full shell and they all can live together in the valence shell.

Answer 2

A covalent bond is a shared pair of electrons. Unpaired electrons from the outer shell on each atom are paired together to form the covalent bond. For example, two chlorine atoms both have 7 outer shell electrons; 6 are already in pairs; they put together their seventh electron each to form the bond.

Answer 3

Covalent bonds occur when atoms share electrons to attain a full outer shell of electrons. The shared electrons create a bond between the atoms, resulting in a stable molecule. The strength of the covalent bond depends on the number of shared electrons and the overlap of atomic orbitals.

Answer 4

Covalent bonds form by sharing electrons. They share the valence electrons.

Answer 5

The valence electrons are shared between two or more atoms.

Answer 6

When atoms share electrons, as they do in covalent bonds, it creates a force that holds the atoms together.

Answer 7

Covalent bonds come about when two atoms (usually non-metals) share a pair of electrons in order to acheive full outer orbitals.
