How to draw Molecular Orbital Diagram of O2 -Chemistry

Molecular orbital (MO) theory explains the construction of molecular orbital diagram on the basis of following main points . 1.Formation of MOs: Atomic orbitals(AOs) linearly combine with each other to form equal number of molecular orbitals (MOs). 2.Energy of MOs: Half of the molecular orbitals (MOs) having energy lower than the atomic orbitals are called …

Formation of Ammonium ion (NH4+) -Coordinate Bond-Chemical Bonding

How is NH4+ ion formed? Formation of Ammonium ion: When ammonia (NH3) combines with H+ ion, results in the formation of Ammonium ion through a coordinate covalent bond. In ammonia, Nitrogen is a central atom having 5 electrons in its valence shell,3 electrons are shared with 3-H atoms and 1 lone pair of electrons complete …
