I assume that you mean shared, in which case that question has been previously answered by another user.
A covalent bond. As multiple pairs of electrons can be shared.
When atoms lose and gain electrons, an ionic bond will form. When atoms share electrons, a covalent bond will form.
Carbon atoms do not gain electrons to form a covalent bond. Carbon atoms form four covalent bonds by sharing its four valence electrons with the valence electrons of other atoms. These can be single bonds, in which one pair of electrons is shared; double bonds, in which two pairs of electrons are shared; or triple bonds, in which three electrons are shared; or a combination of these.
Atoms form bonds with electrons. When they lose or gain whole electrons, the bond is called an ionic bond, and when two atoms share electrons, the bond is called a covalent bond.
Atoms that do not easily lose electrons form covalent bonds with other atoms. That is, they share electrons.
Two electrons are involved in forming a single bond.
A single covalent bond is formed by two electrons
The valence electrons
3. So it can form three single bonds OR a single bond and a double bond OR one triple bond.
this means that there is a single covalent bond
When two atoms form a compound by sharing valence electrons, it is a covalent bond. This is opposed to an ionic bond which features a full transfer of electrons.
A covalent bond. As multiple pairs of electrons can be shared.
Metals form what is known as a metallic bond. It is somewhat similar to a covalent bond in that the electrons are shared, however, in a covalent bond the electrons are shared by a single molecule, and in a metallic bond, the electrons are shared by all the metallic atoms in that particular object.
Covalent bonds share electrons.
When atoms share electrons, they form a chemical bond, or covalent bond.
When atoms lose and gain electrons, an ionic bond will form. When atoms share electrons, a covalent bond will form.
