ionic bonds vs covalent bonds strength

In ionic bond the positive ion pulls the electron density of the anion towards itself and brings about polarisation of the anion. This causes the development of some covalent character in ionic bond..

. In the previous chapter one has observed the formation of a chemical bond by the transfer of electrons called the ionic bond. Atoms also acquire the stable noble gas configuration of having eight electrons in the outermost shell (called the octect rule) by mutual sha..

Hydrogen bond is much weaker than a covalent bond. The strength of hydrogen bond ranges from 10-40 kJ mol - 1 while that of a normal covalent bond is 400 kJ mol - 1 . Thus, a hydrogen bond is about one-tenth of the ..

Quantum Theory of Covalent Bond - Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is m..

An ionic or electrovalent bond has the following characteristics: An ionic bond is formed due to the coulombic attraction between the positively and negatively charged ions. An ionic bond is non-directional i.e., the strength..

Comparison Between Single, Double and Triple Covalent Bonds - Single, double and triple covalent bonds differ from each other in the following ways. Single bond is formed by the sharing of one electron pair, (two electrons); a double bond ..

Bonding in Metallic Solids - More than 80 elements in the periodic table are metals. Metals are solids at ordinary temperature and pressure, with the exception (of mercury and gallium). Metals have characteristic properties such as: High thermal and electrical conductivity. Luster and hig..

The attractive force, which binds various metal atoms, is called metallic bond. The metallic bond is neither a covalent nor an ionic bond..

. The hydrogen bond is represented by dotted line (). For e.g., in case of hydrogen fluoride the hydrogen bond exists between H atom of one molecule and fluorine atom of another molecule. It may be noted that the hydrogen atom is acting as a bridge between the electronegative at..

Mixed Bonding - Apart from coordinate covalent compounds, there are some compounds, which contain both ionic and covalent compounds. For example, sodium hydroxide In sodium hydroxide, there is an ionic bond between sodium ion Na + and hydr..
