classification of elements and periodicity in properties
... The properties of elements are due to the distribution of electrons in orbitals of the atom. The long form of periodic table is based on the Bohr’s model of atom. It is the graphical representation of aufbau principle. It successfully explains the periodicities of properties of elements. Now let us ...

Distinguishing the Atom Reading
... A glance back at Table 4.1 on page 107 shows that the actual mass of a proton or a neutron is very small (1.67ñ10Ź24 g). The mass of an electron is 9.11ñ10Ź28 g, which is negligible in comparison. Given these values, the mass of even the largest atom is incredibly small. Since the 1920s, it has ...
