Describe chemical bonds VideoTYPES OF CHEMICAL BONDING - Animation describe chemical bonds.
Chemical bonding describes a variety of interactions that hold atoms together in chemical compounds. Chemical bonds are the connections between atoms in a molecule. These bonds include both strong intramolecular interactions, such as covalent and ionic bonds.
They are related to weaker intermolecular forces, such as dipole-dipole interactions, the London dispersion forces, and hydrogen bonding. The weaker forces will be discussed in a later concept. Chemical bonds : This pictures shows examples of chemical bonding using Lewis dot notation. Hydrogen and carbon are not bonded, while in water there is a describe chemical bonds bond between each hydrogen and oxygen.
Bonds, especially covalent bonds, are describe chemical bonds represented descrlbe lines between bonded atoms. Acetylene has a triple bond, a special type of covalent bond that will be discussed later. Chemical bonds are the forces of attraction that tie atoms together. The nature of the interaction between the atoms depends on their relative electronegativity. Atoms with equal or similar electronegativity form covalent bonds, in which the valence electron density is shared between the two atoms.
The electron density resides between the atoms and is chemiccal to both nuclei. This type of bond forms most frequently between two non- metals. When there is a greater electronegativity difference than between covalently bonded atoms, the pair of atoms usually forms describe chemical bonds polar covalent bond. The electrons are still shared between the atoms, but the electrons are not equally attracted to both elements. As a result, the electrons tend to be found near one particular atom most of the time.
Again, polar covalent bonds tend to occur between non-metals. Finally, for atoms with the largest electronegativity differences such as metals bonding with nonmetalsthe bonding interaction is called ionic, and the valence electrons are typically represented as being transferred from the metal atom to the nonmetal.
Introduction to Bonding
Once the electrons have been transferred to the non-metal, both the metal and the non-metal are considered to be ions. The two oppositely charged ions attract each other to form an ionic compound. Covalent interactions are directional and depend on orbital overlap, while ionic interactions have no particular directionality.]
