when energy is supplied to an atom while adding an electron. concluding the trends of properties in the periodic table from above, we can say that the elements at the two extremities of the periodic table are highly reactive (note: noble gases have completely filled shells; hence they are ...
the electron cloud forming the shell of an atom does not have any fixed shape which makes it difficult to determine the atomic size of an atom. so we can say that practically we cannot determine the size of an individual atom. recommended videos trends in the periodic table moving down a ...
Jean-Charles Galissard de Marignac was a Swiss chemist whose work with atomic weights suggested the possibility of isotopes and the packing fraction of nuclei and whose study of the rare-earth elements led to his discovery of ytterbium in 1878 and codisc
atomic valance electron divided by atomic volume1. Consequently, as the product of bulk modulus and atomic volume, the atomic stiffness also shows periodic dependence upon the atomic number. With the table of parametrized atomic stiffness (Si) for each element, the bulk moduli for compounds can ...

In fact, one can say that the “iron age” of civilization is being replaced by a “polymer age,” for in some countries the total volume of polymers now produced exceeds that of iron. The scope of chemistry The days are long past when one person could hope to have a detailed ...
