Third Row Elements
The third row elements are from sodium to argon. The build up of these eight elements proceeds exactly in the same manner as discussed above. Here 3s- and 3p-orbitals are filled in place of 2s- and 2p-orbitals as has been done in case of Li to Ne. For e.g., the electronic..

1. There are 18 vertical columns or groups. These are further sub-divided into A and B (groups I to VII), VIII group and zero group. 2. Member of the same group have similar electronic configuration of the valence shell and thus show same valency. 3. Elements..
Merits of the long form of the periodic table
This classification is based on the most fundamental property of the elements - the atomic number, so it is more accurate. With the atomic number as the basis of this classification, the position of isotopes in one place is justified. The systematic grouping of elements ..
Elemental carbon
Symbol: C Atomic number : 6 Atomic mass: 12 (most common isotope) Electronic configuration: 1s 2 ,2s 2 ,2p 2 Position in the periodic table: Period II Group IV Carbon occurs in the free state as well as combined state. The following schematic ch..

Valence electrons of an atom are responsible for chemical reactions as they take part in them. Elements having same number of valence electrons in their atoms possess similar chemical properties. All alkali metals have one valence electron in their atom. T..
Covalent Compounds and Periodic Table
Covalent compounds are formed by the sharing of electrons by atoms of non-metallic elements between groups IVA and VIIA. The elements of these groups react with one another by sharing election pairs. Thus, the valency of an element in a covalent molecule is e..
