molecular formula

Number average molecular mass is obtained by dividing the total molecular mass of the sample by total number of molecules...

Molecular hydrides are formed by the combination of elements of comparatively higher electronegativity as of p block elements. These bonds are mostly covalent in character with partly ionic character too (for example, in HF). These hydrides, therefore have molecular lattices he..

Rules for Filling Molecular Orbitals - The following rules are followed for filling up molecular orbitals with electrons in order to write molecular configurations: 1. The molecular orbital having the lowest energy is filled first. This is in accordance with ..

Molecular orbital theory was proposed by F. Hund and R.S. Mulliken in 1932. The basic idea of molecular orbital theory is that atomic orbitals of individual atoms combine to form molecular orbitals. The electrons in molecules are present in the molecular..

Gram molecular mass of a substance is the relative molecular mass of the substance, expressed in grams. It is also referred to as gram-mole. of some molecules is expressed in table. Gram Molecular Massof Some Molecul..

Kinetic Molecular Theory of Gases - In order to explain the observed behaviour of gases, a model was proposed based on the molecular and kinetic concept of gas molecules. This model takes into account the particulate nature of matter and the constant movement of particl..

Relative molecular mass shows the number of times a molecule is denser than a hydrogen atom or one amu. It is expressed as the ratio of the mass of a molecule of a substance to the mass of one amu (or to one atom of hydrogen..
