Chemical Bond

Lewis structures are very useful to predict whether ionic or covalent bonds will form between certain elements, and in what ratio they will combine. VSEPR…

Sometimes covalently-bonded atoms have a share in fewer than 8 electrons e.g. Be in BeCl2, B in BCl3. Be and B have very high ionization…

Electrons can either be core electrons or valence electrons. The valence electrons are the outermost electrons of an atom. As orbitals are filled, core electrons…

Noble gases are He, Ne, Ar, Kr, Xe, Rn. Helium has a filled shell of 2 electrons. All the rest have 8 electrons in their…

Changes in electron distribution are best described using Oxidation Numbers. Oxidation Number (O.N.) is a way of describing how the electron density around an atom…

Covalent bonding occurs when too many electrons (typically 3 or more) have to be transferred for ionic bonding to be energetically favourable. Outer octet achieved…

Drawing atoms and ions with all the orbits or orbitals is time consuming. We usually draw Lewis diagrams to represent the way that electrons form…

Electrovalent bond: The electrostatic force of attraction which holds the oppositely charged ions together is known as ionic bond or electrovalent bond. We can understand…

The force which binds together the atoms of metals is called metallic bond. All the characteristics metallic properties can be explained on the basis of…

The attractive force which holds together the constituent particles (atoms, ions or molecules) in a chemical species is known as chemical bond. Example: Two atoms…
