Multiple Covalent Bonds
A covalent bond is the force of attraction that holds together two atoms that share a pair of valence electrons. The shared electrons are attracted to the nuclei of both atoms. This forms a molecule consisting of two or more atoms. Covalent bonds form only between atoms of nonmetals.
What is the sharing of electrons between two atoms?
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
When electrons are shared between two atoms, they make a bond called a covalent bond. Because two atoms are sharing one pair of electrons, this covalent bond is called a single bond. … The bonding electron pair makes the covalent bond.
What does sharing valence electrons mean?
Electron ‘sharing’ occurs when the electrons in the outermost electron shell, or valence shell electrons, from one atom can be used to complete the outermost electron shell of another atom without being permanently transferred, as occurs in the formation of an ion.
When electrons are shared between two atoms, they make a bond called a covalent bond. Because two atoms are sharing one pair of electrons, this covalent bond is called a single bond.
What is holding atoms together?
Atoms can be held together by chemical bonds. When atoms form bonds, they can achieve a stable electron arrangement. To achieve a stable electron arrangement atoms can lose, gain or share electrons. There are different types of bonds that hold atoms together.
Why do electrons like to be in pairs?
It is due to the fact that even though electrons have negative charge they are bound to the nucleus by the attraction force from the nucleus and thus they have to somehow be around the nucleus and at the same time be in the lowest possible energy situation.
