anomalous position of hydrogen in the periodic table

Position of Hydrogen in the Periodic Table - Hydrogen is the first element of the periodic table. Its atomic number is 1, which indicates the presence of only one electron in the atom of hydrogen. This electron is prese..

Hydrogen is the first element of the periodic table. Its atomic number is 1, which indicates the presence of only one electron in the atom of hydrogen. This electron is present in its first shell. Hydrogen resembles both alkali metals (group I..

Advantages of Long form Periodic Table - 1. The classification of elements is based on the atomic number, which is a more fundamental property. 2. The reason for placing isotopes at one place is justified as the classification is on the basis of atomic number. 3. It ex..

All elements in the periodic table have been classified as metals and non-metals. The non-metals are placed on the right hand side of the periodic table..

Anomalous Behavior of Oxygen - Like all other first elements of the groups, oxygen also differs from its family members. The anomalous behavior of oxygen is due to its (i) small size (ii) high value of ionization energy and electronegativity (iii) absence of d-orbitals in the va..
