mole concept a
... In the previous section we have learned that a mole of a substance is that amount which contains as many elementary entities as there are atoms in exactly 0.012 kilogram or 12 gram of the carbon-12 isotope. This definition gives us a method by which we can find out the amount of a substance (in mole ...

... The mass of an atom depends upon the number of protons and neutrons present in it. As the atoms are extremely small particles, it is difficult to weigh them directly. For example the mass of single hydrogen (H) atom, is 1.6x10-24g (0.000 000 000 000 000 000 000 0016g). Clearly we cannot weigh a hydr ...

Chemical Bonding and Molecular Geometry
... As you have learned, ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds c ...
