Isotopes and Mass Spectrometry

An atom is the smallest unit which forms the basis of innumerable chemical properties that are exhibited by an element. The scope of reactions although primarily influenced by the interaction of electrons, the number of protons differentiates an element from every other element. Neutrons, although not changing the chemical properties radically, do however play a ...

Mole and Equations

CALCULATIONS FROM EQUATIONS Amounts of substances, the mole , molar mass, molar volume of gases (24 litre/dm3) at room temperature and pressure, the Avogadro constant and their use in calculations. (Determination of the Avogadro constant is not required.) A major problem confronting a chemist when carrying out reactions is to try and understand what they ...
