Ionic Bonding | Chemical Bonding | Siyavula

Ionic bonding takes place when the difference in electronegativity between the two atoms is more than \(\text{1,7}\). This usually happens when a metal atom bonds with a non-metal atom. When the difference in electronegativity is large, one atom will attract the shared electron pair much more strongly than the other, causing electrons to be transferred to the atom with higher electronegativity.

Types of Chemical Bonds | Chemistry [Master]

Chemical bonds 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…

27/1/2011· The mathematical equations chemists use to describe covalent bonding can be solved to predict the regions of space surrounding the molecule in which these electrons are likely to be found. A particularly useful appliion of these calculations generates a molecular surface that is color coded to show electron density surrounding the molecule.
