What do atoms form when they share electron pairs
What is a metallic bond?
All atoms, except those of the noble gases, have a tendency to move their valence electrons in a manner that allows them to achieve a stable noble-gas electron configuration. The valence electrons can either be transferred between atoms or shared. When electrons are transferred from one atom to another, an ionic bond is formed. When two atoms share valence electrons, a covalent bond is formed. Atoms in a covalent molecule are held together by the electrostatic force of attraction between the positive nuclei of the atoms and the negative charge of the shared electron pairs between them.
What determines the degree of polarity in a bond?
The polarity of a bond is determined by the electronegativity of the atoms bonded. If the difference between the electronegativity values for both atoms is small enough to prevent an ionic bond but large enough to be
significantly different, a polar covalent bond is formed.
What is a polar covalent bond?
A polar covalent bond is a type of bond between two or more atoms in which the atoms do not share their pair of electrons equally. In this type of bond, one of the atoms is stronger than the other and attracts the electrons so that they spend more time closer to the stronger atom.
How is a coordinate covalent bond different from normal covalent bonds?
Coordinate covalent bonds, also known as coordinate links or semipolar bonds, are different from normal covalent bonds because both of the electrons that are shared by the bonded atoms originally come from the same atom. This contrasts with normal covalent bonds, in which each atom gives up one of the two electrons that form the shared electron pair.
